Justin Gatlin, 34, has achieved tremendous career longevity for a sprinter. At his first Olympics, in 2004, the Brooklyn native took home a medal of every color—gold in the 100m, silver in the 4x100m and bronze in the 200m. He was forced to miss the 2008 Games while serving a four-year doping ban. Then at the 2012 Olympics, he added a 100m bronze medal to his collection. At the 2015 World Championships, he finished second to Usain Bolt in both the 100m and 200m.
