Reigning Olympic champions Omar McLeod, Derek Drouin and Christian Taylor will risk their bragging rights Saturday in "Rio Rematches" to highlight the 108th Drake Relays at Des Moines, Iowa.
Jamaica's McLeod will face 2012 Olympic champion Aries Merritt of the United States in a men's 110m hurdles showcase while Canadian high jumper Drouin and US 2012 and 2016 Olympic triple jump champion Christian Taylor will be challenged by Rio rivals in feature events.
And Grenada's Kirani James, the 2012 Olympic men's 400 champion who was second at Rio, will face Rio bronze medalist LaShawn Merritt and two of his Rio 4x400 relay gold teammates, Tony McQuay and David Verburg, in the 400.
In all, 10 Olympic champions, 30 medalists and 68 Olympians will compete in the meet.
Other Olympic gold medalists include Americans Dawn Harper-Nelson, the 2008 Beijing champion and 2012 London runner-up in the women's 100 hurdles, and Brittney Reese, the 2012 winner and 2016 runner-up in the women's long jump.
