The first of 14 Diamond League meets is Friday in Doha, featuring several of the U.S.’ biggest hopes for Olympic track and field gold in Rio de Janeiro next year.
Justin Gatlin went undefeated in the 100m and 200m last season. Allyson Felix (200m) and Dawn Harper-Nelson (100m hurdles) were also fastest in the world in their events in 2014. Sanya Richards-Ross and Francena McCorory are the world’s best in the 400m. Brittney Reese has won every global meet long jump she’s entered since 2009.
They’re all entered in Doha, along with more Olympic champions including Great Britain’s Mo Farah and Australia’s Sally Pearson.
