Coby Miller (born October 19, 1976) is an American track and field athlete, who specialises in the sprint events. In his career, he recorded a sub-10 second personal best in the 100 meters and a sub-20 second best in the 200 meters. In the latter distance, he won the 1999 Summer Universiade and reached the 2000 Sydney Olympics final. He suffered leg injuries in the 2001 and 2002 seasons, but returned in late 2002 as part of the gold-medal-winning American 4 x 100 m relay team at the IAAF World Cup, breaking the championship record. He ran under ten seconds in the 100 m Olympics Trials in 2004, but failed to qualify for the event. However, he won an Olympic silver medal at the 2004 Athens Games as part of the American 4 x 100 m relay team. At his peak he was regularly ranked among the top ten American sprinters. Career Miller had his first successes as a collegiate athlete at Auburn University; in 1999 he won the 200 m at the NCAA indoor championships and came second in the outdoor championships. He also enjoyed international success that year, winning the 200 m at the Summer Universiade. He set a 200 m personal best of 19.96 seconds at the 2000 United States Olympic Trials, and reached the 200 m final at the Sydney Olympics. He qualified for the IAAF Grand Prix Final in the 100 m and finished in fourth place. The following year he became the 2001 American indoor champion over 200 m, running a world leading time. However, a pile-up at the finish line resulted in a broken fibula, ruling him out for the rest of the athletics season. This included the 2001 IAAF World Indoor Championships in which he was previously a strong medal contender. The following year he missed much of the indoor track season due to hamstring problems, which were a knock-on effect of his previous injury. Upon his return in 2002 he won medals at a number of track meets in both the 100 and 200 m, including a personal best-equalling win of 9.98 seconds in the 100 m at Gresham. He again reached the Grand Prix Final but finished last. However, Tim Montgomery and Dwain Chambers who finished first and second later tested positive for banned substances and Miller was upgraded to sixth place.
