The track and field competition at the 2016 Olympic Games in Rio de Janeiro starts a year from today on Aug. 12, 2016. Although the U.S. team will be selected at the 2016 U.S. Olympic Trials—the marathon trials are on Feb. 13 in Los Angeles; track and field takes place July 1-10 in Eugene, Ore.—here’s a look at 20 of the most likely candidates to make the team in events from the 800m to the marathon in 2016. Some are longtime stars, others are youngsters on the rise, but there are also a lot of talented runners not on the list. The beauty of the American system is that there are no sure things. You’ve got to finish in the top three at the trials (and have the qualifying time) to earn a ticket to Rio. Many of these runners will probably make the team, but others will not. Who will rise to the occasion? The Road to Rio has begun!
