John Capel Jr. (born October 27, 1978) is an American former track and field athlete who was a world champion sprinter.

[1] Capel played in every game as a true freshman in 1998, earning his only career start when the team opened with a three-receiver formation against South Carolina.

He did not participate in spring football drills due to schedule conflicts with his commitments to the school's track team.

He ran a 10.12 100 meters, a mark that ranks second best in University of Florida history, behind only Olympic medalist Dennis Mitchell.

Capel tested positive in 2004 and then again at the IAAF Norwich Union Indoor Grand Prix in February 2006, that time for a cannabinoid, which resulted in a two-year ban from track.

[4] Since his two-year ban for testing positive in 2006, he has become clean, and returned to competition, which he attributes to his then 7-year-old daughter searching for his name online and learning of his past troubles.

He failed to advance out of the semifinals, but recorded a time of 10.06 seconds: a strong performance after two years away from track competition.

[6] When not competing in track meets, Capel worked for Flagstone Pavers in Brooksville, Florida, driving a forklift and picking defective blocks from outgoing orders.

He also served as a coach for track and field and football at his alma mater, Hernando High School in Brooksville, Florida.

As of August 2024, Capel holds three track records for 200 metres including Athens, Georgia, USA (19.99, 1999), Boise, Idaho (19.87, 1999) and Sacramento, California (19.85, 2000).
