Join us for more live coverage tomorrow. LIVE REPORT ENDS.
2210 GMT: Commentators are already turning their attention to what Bolt might achieve in the 200m, as is his teammate Yohan Blake who tweets: "Big up @UsainBolt! You deserved that one. Big up Jamaica! Now it is on to the two!"
Think that's got to be our TWEET OF THE DAY. And as things wrap up here tonight, we'll also leave you with the PHOTO OF THE DAY: Usain Bolt cruising to victory in the 100m final in another iconic Olympic moment.
2158 GMT: Asafa Powell, who limped over the line in eight place in 11.99 seconds in the 100m final, says he's "very disappointed" and blames a groin injury.
"I injured myself. I just couldn't push. I tried in the semifinal to release the tension. I got out very well and stumbled... I need to fix this," he says.
2145 GMT: Mayor of London Boris Johnson @MayorofLondon tweets: "Dazzling evening in the Olympic stadium watching the world's fastest man blaze to glory. Terrific Olympic moment."
2137 GMT: It didn't stop with the 100m, of course... While the world was abuzz with Bolt fever, Hungary's Kristzian Pars won the MEN'S HAMMER GOLD.
With a winning mark of 80.59m, he beat defending champion Primoz Kozmus, who threw a season's best of 79.36m. Japan's 2004 gold medallist Koji Murofushi took bronze, also with a season's best of 78.71m.
2134 GMT: It was bitter disappointment for USA's Tyson Gay, who came in fourth -- one hundredth of a second off his teammate Gatlin in 9.80sec.
He says: "It's tough, but I have no excuses, I gave my all. Everybody came together and made me the best I can be. I tried my best."
A third American, Ryan Bailey, was fifth in 9.88.
2126 GMT: Just to qualify the statement that Bolt is the first to retain the title... He's actually the first man to successfully defend the100m title on the track.
Carl Lewis won in 1984 and 1988 -- but was awarded the latter only after Ben Johnson was stripped of it in a doping scandal.
2120 GMT: Blake resigns himself to second place behind the big man: "He is the fastest man in the world and I've got a silver medal. What more can I ask for?" he says.
"To be the second-fastest man in the world behind BOLT is an honour."
Indeed, hardly a failure.
2115 GMT: Bolt admits his training partner Blake works harder than him but says: "I knew what I needed to do and I have great talent. He will do better next time because he was a little bit stressed this time."
2110 GMT: Interviewed at the side of the track, Bolt tells the BBC : "I was happy when I went out in the first round, I felt I could do this. I was slightly worried about my start.
"It was not the best reaction in the world but I stopped worrying about it and executed it and it worked.
"I said it on the track, people can talk, all they can do is talk. When it comes to championships I bring it. I knew [the crowd] would be like this, I can feel that energy and I am extremely happy."
2105 GMT: He does his trademark bow and arrow pose, to chants of "Usain, Usain!" resounding around the stadium.
2100 GMT: Bolt's playing to the crowds now, draped in the Jamaican flag and lapping up the glory with training partner Blake. He's the first person EVER to retain the 100m crown.
2055 GMT: It's a new Olympic record for Bolt and the second fastest time in history!!
Fellow Jamaican Yohan Blake takes silver in 9.75 secs, with America's Justin Gatlin claiming bronze in 9.79 secs.

THE 100m FINAL IS NEXT... Need we say more.
2045 GMT: Sanya Richards-Ross says she "fought all the way to the end" to claim 400m gold.
"This win is impossible to describe," she tells reporters. "I worked so hard for that and I prepared for this moment over and over for the last four years."
2039 GMT: A great show from Ezekiel Kemboi! He collapses to the ground after his massive victory before jumping to his feet and dancing before the crowds.
He won the race in 8min 18.56sec ahead of France's Mahiedine Mekhissi-Benabbad who clocked 8:19.08 for silver, while Kenya's Abel Kiprop Mutai claimed bronze (8:19.73).

It means the two teams have eight points, one more than Pakistan, after each has played four of their five group games.
2027 GMT: More details on that triple jump final earlier... Kazakhstan's Olga Rypakova leaped to gold with a season's best of 14.98 metres.
Colombian Caterina Ibarguen claimed silver with 14.80m, with Ukraine's current world champion Olha Salduha settling for bronze at 14.79m.
2022 GMT: Only Richards-Ross could look this glamorous after storming an Olympic 400m final.
The home crowd cheers for their Ohourugu but in equal measure for the American, draped in the stars and stripes, after a stunning run.
US basketball player Kevin Durant @KDTrey5 tweets: "Yessir! congrats to my girl Sanya Richards-Ross on the Gold!!"
2014 GMT: Richards-Ross powered home in 49.55 secs, well ahead of the competition. It was a close call for second and third, but Britain's Christine Ohourugu snatched silver in 49.70 secs, with America's DeeDee Trotter claiming bronze in 49.72secs.

James was seen swapping his name tag with Pistorius after their race and later said: "Oscar is a very special guy and I was honoured to be out here on the track with him."
1955 GMT: ATHLETICS: It's bad news for South Africa's Oscar Pistorius as he returns to the track tonight for the 400m semi-final.
The double amputee who runs on carbon fibre blades came in last in his heat, won by Kirani James of Granada.
But the dream's not over... he should be up again in the 4x400m relay.
1946 GMT: DIVING: In the excitement of the 100m dash, this gold slipped under our radar, so apologies for the delay...
CHINA'S WU MINXIA WINS WOMEN'S 3m SPRINGBOARD DIVING GOLD.
It means world champion Wu draws level with Guo Jingjing as the most-decorated diver at the Olympics with six medals. She totalled 414.00 points from her five dives to beat teammate He Zi (379.20) and Mexico's Laura Sanchez (362.40).
It's China's fifth gold medal from five events... can they sweep all eight?
1941 GMT: Moroccan runner Abdalaati Iguider produced a season's best of 3:33.99 to win the second heat of that 1500m semi, qualifying for the final along with Silas Kiplagat, Nicholas Willis, Nixon Kiplimo Chepseba and Matthew Centrowitz.
1938 GMT: Back in the stadium the men's 1500 semi-finals have been taking place and it was Morroco's Taoufik Makhloufi who crossed the line first in heat one, with a time of 3:42.25.
Defending champion Asbel Kiprop of Kenya was second in 3:42.92 and qualifies for Tuesday's final along with Makhloufi and Mekonnen Gebremedhin, Leonel Manzano and Henrik Ingebrigtsen.
1932 GMT: Seems Chambers just ran out of gas in that semi-final. He says: "I wanted to do well and get into the final but I'm happy to be here, I really am. I am gutted that I didn't make the final but you can you can't have it all.
"It was worth every moment of it, to feel that roar and be in this atmosphere again, money can't buy that and I'm glad I fought this hard to get to this position.
Asked about Bolt, he adds: "He's going to be flying, he's flying, I thought I had him till about 60 metres and that was it, I ran out of petrol, man! (LAUGHS) The kid's got talent." NOTE - by kid he meant Bolt.
1927 GMT: Jamaica's Yohan Blake plays it cools after the semis, telling reporters: "I am the beast, so I have to go back and stay focused for the final."
1921 GMT: Great Britain's Adam Gemili is also out of the running for the 100m final, after finishing third in his semi heat.
But there's time yet for the 18-year-old, who only started sprinting in January. He tells BBC radio he'll "stick with athletics and see how it goes."
1915 GMT: "There will be no miraculous Olympic medal for former drugs cheat Dwain Chambers," notes AFP's Charles Irwin.
"Chambers had successfully fought a legal battle to overrule a British Olympic Association bylaw banning athletes who had served doping bans from competing at Olympics.
"He finished fourth in his semi-final but left the track grinning as for him he had got his medal by competing."
1906 GMT: So, the line up for tonight's 100m final (2050 GMT) is: Gatlin, Blake, Bolt, Gay, Martina, Powell, Bailey, Thompson.
Gatlin was the fastest qualifier...could he surprise us later? Or will Bolt give the world what they're waiting for?
1901 GMT: Jamaica's Yohan Blake wins the next heat in 9.85secs to put him through to the final, along with America's Tyson Gay who came in second with 9.90 secs.
1858 GMT: The lightening Bolt -- not actually known for his fast starts -- was surprisingly quick off the starting blocks and instantly took the lead. When it was clearly in the bag, he turned his head to the roaring crowds, slowing as he came to the finish.
It begs the question, what time will he make tonight? He clearly has more in him....
Ryan Bailey finished that heat in second place with 9.96 secs to also qualify for the final.
1853 GMT: And BOLT DOES IT AGAIN! He wins the heat in 9.87 secs and is through to the final -- as if we ever doubted it!
1850 GMT: Bolt on the track now wearing a Jamaica beanie and headphones. Crowds clapping and cheering.
Hat's off now and they're limbering up...
The top two in each heat go through, plus the two fastest losers. Britain's Dwain Chambers is also on the starting line here.
1845 GMT And America's Justin Gatlin wins the first heat with 9.82 secs. Second to qualify is Churandy Martina of the Netherlands with 9.91 secs.
1840 GMT: AFP's John Weaver is in the stadium for the big one up next...He says: "The stadium is drenched by the evening sun and the crowd is waiting for something to happen after last night's heroics by the British team. They won't need to wait long with the 100m semi final up next....
1835 GMT: THLETICS: America's Perri Shakes-Drayton storms through her heat of the women's 400m hurdles. She had a huge lead throughout, but slowed a little at the end to finish in 54.62secs.
1824 GMT: Iran's Hamid Reihanpour claimed the title over Azerbaijan's Rovshan Bayramov who won silver with Peter Modos of Hungary and Mingiyan Semenov of Russian taking the two bronze medals up for grabs.
1818 GMT: IRAN'S REIHANPOUR WINS GRECO-ROMAN 55kg WRESTLING GOLD.
1810 GMT: ATHLETICS: Another night of track and field is under way at the stadium and it's the big one! Men's 100m semis up in 35 minutes, followed by the finals at 2050 GMT. But first it's the women's 400m hurdles heats...
1803 GMT: CYCLING: Our man Justin signs off from the velodrome: "That is the competition over for Sunday. Back on Monday with the men's sprint semis !
"Hansen, meanwhile, is overjoyed. If he doesn't get signed by a professional road team soon then they're missing out on a great rider. Oh, and it's nice to hear a different national anthem for a change. It is the Olympics after all."
1757 GMT: BELARUS PAIR WIN MIXED DOUBLES GOLD.
Top seeds Max Mirnyi and Victoria Azarenka defeated Britain's Andy Murray and Laura Robson 2-6, 6-3, 10/8
Murray will have to console himself with that small victory over Federer earlier.
1752 GMT: TENNIS: In a break from the track, Russia's Maria Kirilenko and Nadia Petrova have claimed bronze in the women's doubles tournament. They beat Americans Liezel Huber and Lisa Raymond 4-6 6-4 6-1.
1747 GMT: But it's not enough for the Briton... DENMARK'S HANSEN WINS MEN'S TRACK CYCLING OMNIUM GOLD.
Denmark's Lasse Norman Hansen was crowned the men's inaugural Olympic omnium champion after a stunning finish to his six-events.
Frenchman Bryan Coquard finished second to take the silver with Britain's Ed Clancy claiming bronze.
1742 GMT: More from Justin..."Amazing. Clancy, an endurance rider, nearly beats Sir Chris Hoy's Olympic record for 1km time trial. He hot clocked the 1min 00.711sec record set in Athens, stopping the clock at 1:00.981."
1737 GMT: "Crowd going absolutely nuts trying to will Clancy on to a perfect kilo ride !!" says Justin of the British rider.
1734 GMT: CYCLING: In the velodrome the crowd has been kept entertained with the dreaded "kiss cam" during a brief pause -- spectators not all overly keen to participate.
But now to the serious action... "The men's final event in the omnium, the 1 km time trial, has started," reports Justin Davis. "Time soon for the first (and last) gold medal of Sunday's track programme."
1727 GMT: Taking advantage of a brief lull in events, here's a quick recap of today's action so far:
+ Andy Murray rode a wave of British euphoria as he routed Roger Federer for tennis gold, defeating the Swiss 6-2, 6-1, 6-4.
+ American Williams sisters Serena and Venus beat Andrea Hlavackova and Lucie Hradecka 6-4, 6-4 to claim their third Olympics doubles title.
+ Britain's Ben Ainslie won his fourth consecutive sailing gold, in the Finn class, becoming the sport's most successful Olympian.
+ The women's marathon was won by Ethiopian Tiki Gelana in the opening athletics medal of the day.
But, of course, the real action is still to come when Bolt and co return to the track later for the 100m semi-final (1845 GMT) and final (2050 GMT).
1717 GMT: WEIGHTLIFTING: It's a gold medal for Zhou after that world record record of 333kg in the +75kg category. She broke her old mark from last year's world championships of 328kg and matched South Korean Jang Mi-Ran's world marker of 187kg in the clean and jerk.
The stunning competition saw European champion Tatiana Kashirina of Russia set a new snatch world record of 151kg as she missed out on gold by just one kilo.
Hripsime Khurshudyan of Armenia claimed bronze with a total lift of 294kg.
1710 GMT: CYCLING: Justin Davis has more on those women's sprint quarter finals: "No upsets so far as Kristina Vogel, a gold winner in the women's team sprint with teammate Miriam Welte, beats Ukraine's Lyubov Shulika.
"Two heats left, and because there were no deciders required after the men's sprint quarter-finals the repechages will be up next. After a short breather, of course."
1704 GMT: WEIGHTLIFTING: Unbelieveable! Russia's Kashirina has set yet another two world records -- in the +78kg and +75kg categories. But these were both then surpassed by China's Zhou Lulu. More details to follow.
1658 GMT: Anna Meares makes is look so easy, hardly an acceleration from the Aussie as she beats Canada's Monique Sullivan to go through to the quarter finals, says Justin.
Natasha Hansen was hoping to get the jump on Chinese ace Shuang Guo, but Guo is too fast for her, and the New Zealands goes spinning into the second round repechages.
1649 GMT: These cycling sprint races come thick and fast. Now it's the women's sprint second round. Six heats, winners go straight to quarter-finals, losers get a second chance in repechages.
"Crowd goes wild as Pendleton takes another step towards defending her Beijing title," says Justin from the trackside. "What a turn of speed! Dutchwoman Willy Kanis goes into repechages, not the best way to end her career on the track."
1644 GMT: "Gregory Bauge, too, accounts for his opponent -- German muscle man Robert Forstemann," adds Justin. "Shane Perkins also qualifies for the last four after beating American firefighter Jimmy Watkins. Now, it's the final heat.
"Phillip continues his trademark celebrations and sends the crowd wild with a closely fought win over Dmitriev. The big Trinidadian knows how to show when he's happy to have won. He will now meet Jason Kenny in Monday's semis while Bauge meets Perkins."
1640 GMT: CYCLING: We've just had the power riders in the second race of the match sprint quarter-final -- Britain's Jason Kenny v Awang Awang Azizulhasni....
"A nice sporting handshake and Kenny takes it in commanding fashion," reports Justin Davis.
"Awang will now turn his attention to Tuesday's keirin while Kenny will meet Njisane Phillip in the semis -- if the Trinidad rider beats Russia's Dmitriev."
1633 GMT: TENNIS: The emotion coming out of Wimbledon is almost unbearable! First tearful scenes as Murray beat Federer, now Argentina's Juan Martin del Potro says he is "crying with happiness" after winning bronze.
Del Potro, who left Centre Court in tears after losing to Federer on Friday, beat world number two Novak Djokovic 7-5, 6-4
"I don't have the words to explain, he says. "It's similar to winning a Grand Slam or maybe even bigger. It's amazing."
1625 GMT: WEIGHTLIFTING: Another world record has fallen and this time it's in the hands of Russia's Tatiana Kashirina. She set a new world record in the snatch during over-75kg weightlifting competition, lifting151kg to beat her own previous mark of 148kg set in November.
In fact the 21-year-old broke the record twice, first with her second lift of 149kg and then again with her final snatch.
1620 GMT: And Bell's move pays off. He finishes ahead of Teruel, Bryan Coquard of France and Clancy, although the Briton was a lap down meaning he effectively lost the race. Clancy dropped to fifth overall ahead of the 1 km time trial -- the last of the six disciplines that make up the omnium but one of his strongest races.
1616 GMT: More from Justin: "Hansen is blasting his way round of the bottom of the track trying to make up the lap he lost earlier. He's back in the medals hunt and applause rings around.
"Right, here's another attempt at an attack but it doesn't seem to be gaining ground. Remember, some guys out there are already a lap down, including Aussie gold contender O'Shea, Kiwi Shane Archbold, Clancy and the Belgian Van Hoecke.
"Zach Bell of Canada is off the front, joined by a Spaniard. And here come the counter-attacks for the final few laps!"
1612 GMT: "Dane Lasse Hansen's hopes of a medal look dashed after a crash," adds Justin, "but the crowd gives him a warm hand as he gets back on his bike. It almost took down Britain's Ed Clancy too.
"Now there's an eight-man breakaway trying to get away, and Hansen's chasing like mad to join on...
"...The eight-man break has caught the field, meaning they gain a lap. Clancy has also been caught after a brief attempt to hold off the break by himself."
1610 GMT: CYCLING: "New Zealand's Natasha Hansen, Canadian Monique Sullivan and Dutchwoman Willy Kanis make the second round after winning their respective repechages in the women's sprint," Justin Davis tells us.
"Now, time for the omnium scratch race -- a simple affair of 15 km and 60 laps with the first man over the line winning the race. Who says the omnium is hard to understand?"
1605 GMT: BADMINTON: To fill you in on that earlier Chinese badminton medal haul... China clinched all five badminton gold medals when world champions Cai Yun and Fu Haifeng won the men's doubles, beating Denmark's Mathias Boe and Carsten Mogensen 21-16, 21-15 .
Earlier Lin Dan beat Malaysia's Lee Chong Wei in the single's final. Gracious in his victory, he said of his opponent: “Lee Chong Wei is such a brilliant rival that I treasure the chances to play against him. We are very good friends and I welcome him when he comes to China and hope he comes frequently." That's the spirit!
1559 GMT: Aussie fast man Shane Perkins wins his sprint heat over the American firefighter from California, Jimmy Watkins, Justin tells us.
Next up is the man from Trinidad, Njisane Phillip against Russian Denis Dmitriev, and it's a tight match but Phillip gets the nod after a photo finish.
1552 GMT: Now for the men's heats in the sprint quarter-finals, where they could race three times against each other in the event of a draw after two matches.
"Crowd go wild as GB's Kenny beats Malaysian Awang in a great first match sprint. Kenny looks imperious once again, but here comes the big Frenchman Greg Bauge," says Justin.
"Bauge wins a very tactical heat against another big boy of track's most coveted event, German Robert Forstemann. Did you see those legs? Massive, but not as quick as Bauge's."
1546 GMT: CYCLING: Back at the track, our Justin Davis has been following the women's sprint. First up was Britain's Victoria Pendleton -- the fastest qualifier with an Olympic record -- against Ekaterina Gnidenko of Russia.
"Pendleton coasts past the 19-year-old Russian, who will get a second bite of the cherry in repechages," reports Justin. "Anna Meares, Pendleton's big rival, also coasts into second round after beating Japan's Kayono Maeda.
"All the big women's favourites make it through to second round, with Simona Krupeckaite of Lithuania and Lyubov Shulika winning their heats. "
1538 GMT: GYMNASTICS: While we've been engrossed in the tennis, another gold has fallen, this time for Hungary's Krisztian Berki in the pommel horse final.
He won by the finest of margins, finishing on the same score as Britain's Louis Smith -- 16.066 points. But reigning world champion Berki was awarded gold as his execution score of 9.166 was 0.100 points higher than Smith's. Max Whitlock, another Briton, won the bronze.
1532 GMT: Murray on the podium now as centre court resounds with the national anthem. Then the crowd erupts into cheers as he drapes himself in the Union Jack for photos.
1526 GMT: An explosion of Murray celebration on Twitter, as in many a British living room:
The official Team GB account @TeamG says: "Andy Murray runs up and celebrates with his family, savour this moment. have we ever seen such a deserved victory?"
Mayor of London Boris Johnson tweets: "He's only gone and done it! @andy_murray is champion on the lawns of Wimbledon in straight sets. Good luck for the Mixed final!"
1520 GMT: "I did well," Murray tells the BBC in possibly the understatement of these Games.
1515 GMT: Murray, the tears already flowing, has leapt into the stands and run straight into girlfriend Kim Sears' waiting arms. Federer has walked off the court and Murray is receving a standing ovation.
The final score there was 6-2, 6-1, 6-4 as Murray routed the Swiss great in just one hour and 56 minutes.
1514 GMT: TENNIS: BRITAIN'S ANDY MURRAY TAKES GOLD AGAINST SWITZERLAND'S ROGER FEDERER.
1511 GMT: No matter how well Murray is playing, Federer is not going down without a fight. The score in the final set is now 5-4 -- and it's the biggest service game of Andy Murray's life. The Wimbledon crowd are again on their feet.
1506 GMT: Federer fights back from match point to make the score in the third set 4-3 to Murray.
1503 GMT: "This -- is -- well, let's just not say it": stunned BBC commentators can hardly get the words out as they watch Murray blast through another game.
The gold medal is his for the taking, with the third set standing at 4-2. The crowd at Wimbledon appear beside themselves, and are on their feet for every point.
1459 GMT: Another tweet from Team GB:
"#Tennis We're in awe of what we are witnessing- @Andy_Murray is playing out of his skin + has broken Fed again. 3-2 Murray. #MagicMurray".
1454 GMT: All eyes in Britain have turned towards the tennis. CNN's British talk show host Piers Morgan tweets: "Murray's playing sensational tennis, demolishing the best player ever. Incredible! #TeamGB"
While footballer Fabrice Muamba tweets : "Andy Murray is playing the best tennis I have ever seen him. #come on Murray".
Team GB's official Twitter account adds: "#Tennis Federer holds his first service game of this third set. Come on @Andy_Murray, this game is yours to lose. We believe #MagicMurray".
And Harry Potter actress Emma Watson has tweeted very simply: "Murray Murray Murray .... #olympics2012 ".
1450 GMT: TENNIS: Argentina's Juan Martin del Potro has defeated Serbia's Novak Djokovic to take the bronze medal.
But all eyes are on Centre Court where, a BBC commentator informs us, Roger Federer is in the process of being "wiped out". Now there's a sentence you never though you'd hear anyone say.
Murray has taken the second set and the score is 15-0 in the first game of the third set.
1445 GMT: BADMINTON: CHINA WINS MEN'S DOUBLES TO COMPLETE FIVE-GOLD MEDAL SWEEP
1440 GMT: GYMNASTICS: ROMANIA'S SANDRA IZBASA WINS WOMEN'S VAULT GOLD. Maroney is left wih silver as Russia's Maria Paseka takes bronze.
1436 GMT: Time to go into predicting the future -- Federer's just won his first game in about an hour, making the score 6-2, 5-1.
1435 GMT: TENNIS: Murray has just taken his tenth game in a row, holding Federer to 6-2, 5-0.
Surely Federer will strike back soon, surely. He's one of the greatest tennis players of all time, we all know he won't take this lying down.
1434 GMT: CYCLING: The torrential rain this morning has led to claims of leaks at the velodrome. AFP's Justin Davis, at the arena, tells us:
"Reports of leaks in the roof at the Olympic velodrome track have been confirmed, but played down as 'minor leaks' that will be repaired overnight. So far, no leaks on the track itself and the riders are warming up ahead of the session."
1429 GMT: TENNIS: The official Olympic tennis feed isn't taking sides, of course, but has just tweeted: "Murray breaks and then holds a marathon game saving 6 break points! The Brit now leads 6-2 3-0. Federer is in big trouble! #OlympicTennis".
It has been 45 minutes since Federer won a game -- and Murray has just taken another one, making the score 6-2, 4-0.
1423 GMT: The vault is proving cursed. Now the US's McKayla Maroney who has run in to trouble.
AFP's Tom Williams tweets: "Maroney sits down second vault! Oh dear. How will that affect things? She leaves the mat with a face like thunder."
1407 GMT: GYMNASTICS: Canada's Elsabeth Black has earned the respect of the audience after a painful landing on the vault, climbing to her feet to loud applause despite a score of 0.000.
AFP's Tom Williams says Black wiped a tear away as she lined up for another try -- but, running down the runway again, she is forced to pull up due to injury.
1355 GMT: TENNIS: It's a good thing they've opened the roof at Centre Court. If they hadn't, the roar that just greeted Andy Murrary's 6-2 victory over Federer in the first set might have lifted it right off.
However AFP's Steven Griffiths at Wimbledon, sounds a note of caution for British fans as he points out the Olympic match is so far following a familiar pattern -- Murray won the first set against Federer at their Wimbledon final also.
He lost Wimbledon. Can he keep the momentum going today?
1351 GMT: Ainslie has told the BBC that this has been "the toughest week of my life" and makes it clear this is likely to be his last Olympics.
"You never say never but I don’t think I can sail one of these again," he says. "It’s killing my body… I don’t think you’ll see me in Rio."
1342 GMT: Ben Ainslie's victory gives him the most gold medals of any Olympic sailor. He has been congratulated by the Team GB Twitter account:
"#Sailing #BigBen was really ticking in that race and he is now the greatest Sailing Olympian of all time. An unbelievable achievement!"
1337 GMT: SAILING: GREAT BRITAIN'S BEN AINSLIE WINS RECORD FOURTH GOLD
1333 GMT: AFP's Tom Williams, watching the gymnastics, says Zou hit nearly every landing perfectly.

1316 GMT: The match -- and Murray's bid for two gold medals in one afternoon -- has begun. Win or lose, what must it feel like to be Murrary right now, having played before a home crowd at a Wimbledon final and an Olympic final in the space of a month? He must hear the roar of the crowd in his dreams (nighmares).
As Richard Branson said earlier, no pressure...
1312 GMT: The roof has been opened at Centre Court and Roger Federer, dressed in red, has arrived and is warming up with Andy Murray, clad in blue.
The pair both serve at the same time -- and Federer's ball soars over the net while Murray's slams into it. That's probably not a sign of things to come, though.
1255 GMT: The Williams sisters Serena and Venus high-five their smiling opponents, Czech pair Lucie Hradecka and Andrew Hlavackova, after beating them 6-4, 6-4 to win the gold medal. Add another one to the US tally!

1229 GMT: Gelana can be seen jogging back down the Mall (as if she hasn't had enough running today!) with Ethiopia's flag draped around her shoulders, high-fiving cheering fans. She can't seem to stop smiling.

Imagine hitting the end of a marathon and having to sprint...
1218 GMT: ATHLETICS: It's starting to look like the marathon could come down to a sprint finish, with three runners -- including Russia's Arkhipova -- still together in the lead and less than two kilometres to go.
Mary Keitany, the race favourite, has just fallen back from the leaders' pack, meaning the medals appear to be decided between Arkhipova, Gelana, and Jeptooh, and the race is opening up...
1213 GMT: TENNIS: According to the official Olympics tennis Twitter feed, the Williams sisters have taken the first set 6-4 in 51mins.
1206 GMT: SHOOTING: SOUH KOREA TAKES GOLD IN 50m PISTOL

"Roger is the favorite but there is something magic about Andy these days ...its written in the stars!"
1143 GMT: ATHLETICS: An hour and 45 minutes into the marathon and it's all still very close -- but a definite pack of Kenyan and Ethiopian runners appears to have broken out in the front. They include Mary Keitany, Edna Kiplagat and Priscah Jeptooh of Kenya, and Tiki Gelana, Aselefech Mergia and Mare Dibaba of Ethiopia.
1132 GMT: TENNIS: The action over at Wimbledon is beginning. From the official Olympics Tennis Twitter feed:
"Players on Centre Court warming up for women's dubs gold medal match... Williams/Williams (USA) vs Hlavackova/Hradecka (CZE)".
1112 GMT: ATHLETICS: On that note, AFP's Charles Irwin is inside the athletics stadium today. He tells us:
"Grey skies and pouring rain open the day when Usain Bolt will either attain the legend status he desires or end in disappointment. Either way it will have to be something special to outdo the atmosphere of Saturday.
He adds:"Oscar Pistorius the 'blade runner' also reappears in 400m semi-finals but will be pushed to reach the final. Still the way these games ars going expect the unexpected!"
1108 GMT: London 2012 chair Sebastian Coe, speaking about yesterday's triumphs for Great Britain, has just told an IOC media briefing: "I think it was the greatest day of sport that I have ever witnessed".

Athletes’ spiritual needs at the Olympic Village are being tended to by a team of dozens of multi-faith chaplains.
1042 GMT: ATHLETICS: One of the greatest things about the Olympics is that it brings the little guys as well as the sporting powerhouses to the edge of glory.
To that end, the tiny Atlantic archipelago of Bermuda -- with a land area of 21 square miles -- saw its entire population of just 65,000 people on the edge of their seats yesterday as 27-year-old local Tyrone Smith became the first Bermudian in decades to reach an Olympic final, competing in the men's long jump.
Smith finished 12th -- but, according to his Twitter feed, his final jump (which he unfortunately fouled) was 8.2m. Had the jump been good he could have won the silver medal, doubling Bermuda's entire medal tally and officially becoming the island's most successful Olympic athlete of all time (Bermuda has won just one Olympic medal in its history, with boxer Clarence Hill taking bronze in 1976.)
Smith was hard on himself, apologising to his fans on Twitter, but Bermudians -- to a one proud and amazed that an athlete from their tiny island was able to compete on the world's biggest stage -- were having none of it. "Bro you made everyone proud," Euan Holden tweeted Smith. "Your an olympian keep your head up and your swag on."
1036 GMT: Britons continute to dominate the cycling, with Justin telling us: "As expected, Olympic sprint champion Pendleton blitzes the field in a new Olympic record of 10.724.
"Along with Australian rival Anna Meares, who timed 10.805, the Briton is the only rider to go under 11 seconds -- a strong indicator of her sheer power and speed going into the tournament."
1027 GMT: More from Justin as the patriotic crowd at the velodrome get geared up for Victoria Pendleton to appear. He says:
"Germany's Kristina Vogel is the fastest rider so far in 11.027 but let's see how Vicky Pendleton's legs react when the largely partisan British crowd erupt in a few moments! Australia's Ana Meares, who is last to go, is the world record holder in 10.782."
1009 GMT: CYCLING: Justin Davis has an update for us from the velodrome:
"O'Shea does enough in the 16-lap, 4 km pursuit to take the lead of the omnium standings with two races -- the scratch and the 1 km time trial -- to go. The biggest cheer of the packed velodrome went out to Ed Clancy after he moved up to second overall just two points shy of O'Shea.
"Now it's time for the women's 200m flying lap, the first installement in the long battle for individual sprint glory. After this demonstration of pure speed, in which the last 200m of the flying lap is timed, it's on to a series of duels between the riders battling for track's most prestigious gold."
0957 GMT: ATHLETICS: The women's marathon has gotten under way in central London, with the crowd -- umbrellas up -- letting out a huge roar at the start.
0952 GMT CYCLING: The weather doesn't matter inside the velodrome however, where AFP's Jusin Davis is watching the action unfold. He tells us: "A massive cheer goes up in the velodrome as Britain's Ed Clancy starts the pursuit ride of the six-discipline omnium.
"Clancy already won team pursuit gold with Britain on Friday. He is up against Australia's world champion Glenn O'Shea, a silver winner in the Team pursuit."
0949 GMT: ATHLETICS: The women’s marathon -- set to start in about ten minutes -- will pass by some of London’s most historic landmarks.
It starts and finishes on The Mall, a stone’s throw from Buckingham Palace. The route also takes in the Houses of Parliament, St Paul’s Cathedral, the Tower of London, the River Thames and St James’s Park. All of which would be very scenic if it was not so gloomy and damp out there…
0933 GMT: Meanwhile British legend and double Olympic decathlon medallist Daley Thompson seems to be having a good time getting through security at Olympic Park this morning, tweeting: "Hands up who's idea it was to use the army to do bag search. Inspired they are brilliant. They r trying to get us all to dance!"
In summary, Britons queuing up to go through security in the rain has become an occasion for dancing. Will the country ever recover from Olympic fever?
0931 GMT: While AFP photographer Leon Neal, who has been covering many of the sporting events, tweets: "*looks at torrential rain* 'Bagsy Centre Court!'"
0929 GMT: ATHLETICS: The rain coming down in London can't dampen enthusiasm for the women's marathon this morning, however. AFP's Nilay Silam tells us he saw "thousands" of people lining the route -- many clad in Union Jacks or waving them.
0917 GMT: After Britain's greatest day of sporting glory, it is perhaps fitting that typical British weather seems ready to assert itself today. Ominous clouds are piling up around various sporting venues, and the Met Office has issued a severe weather warning for the London and Souh East England areas, with rain already showering the Olympic Park.
0912 GMT: US singer Josh Groban has also been tweeting about the Olympics this morning: "I really love how London is presenting these games. Totally making it their own...it has heart."
0905 GMT: The velodrome is heating up again already this morning. Britain's track sprint cycling coach Iain Dyer tweets: "Walked in to the velodrome just now; Happy Mondays playing over PA. It's not Monday, but we're Happy nonetheless. W & M sprint today.."
0853 GMT: Pistorius has also this morning retweeted a message he got from none other than Hollywood’s finest Samuel L Jackson:
"Thank you! :)RT @SamuelLJackson: I don't care WHO you are, that's MOVING! SA RUNNER is a true example of Human Determination! Rock On Dude!"
Jackson has been one of the most prolific and entertaining celebrity tweeters of the London 2012 Games -- though, sadly, many of his finest quotes are simply not repeatable here.
0849 GMT:South Africa's Oscar Pistorius, first double amputee to compete in Olympic track athletics, has been on Twitter this morning discussing his preparations for the 400m semi-final later: "12and a half hours till the 400m Semi-Final! Off to smash some breakfast, alittle physio and video session to plan my race. Ahh YEAH!"
0833 GMT: Today is also the first day of the rest of Michael Phelps' life. The most decorated Olympian of all time swam his last race last night, bringing home his 18th gold medal as the US won the men's 4x100m individual medley relay.
The last thing Phelps tweeted yesterday was a retweeted quote from @GreatestQuotes: "'Don't cry because it's over. Smile because it happened.' - Dr. Seuss".
0813 GMT: A total of 23 medals will be decided today, day nine of the London 2012 Games. Other medals to be decided will include the men's badminton singles -- when China's world number one Lin Dan faces Malaysian rival Lee Chong Wei in the latest instalment of their long rivalry -- and, in gymnastics, the apparatus finals for men's floor and pommel horse take place either side of the women's vault.
0810 GMT: Some highlights to look forward to today:
+ Usain Bolt defends his 100m title in one of the most eagerly-awaited sprint finals of all time -- potentially the quickest race in history (Final 2050GMT).
+ Roger Federer and Andy Murray clash in the men's singles tennis final at Wimbledon (not before 1300GMT). Murray insists he will be fully fit after he battled through two hard-fought matches on Saturday to reach the mixed doubles final with Laura Robson.
+ Women's boxing makes its Olympics bow (1230GMT) with the opening bouts in the women's flyweight and lightweight categories.
WELCOME TO AFP'S LIVE REPORT as the host nation gets ready to follow up on its most successful Games day in 104 years, with a rush of medals yesterday that boosted Great Britain to third on the medals table -- though Team GB is still behind China and the US by a considerable distance.
Britons up and down the country are near bursting with pride. As Daily Telegraph features writer Harry Wallop tweets this morning: "The Olympics needs a rest day -- for the spectators. I am drained".
No rest for the athletes, however, with yet another full day of jaw-dropping achievement ahead of us -- not the least of which includes the men's 100m final, billed as the fastest race in history. Can Jamaica's Usain Bolt retain his title?
Stand by for a fuller rundown of what to expect today...
