The 2000 United States Olympic Trials for track and field were held at Hornet Stadium in Sacramento, California. Organised by USA Track and Field, the ten-day competition lasted from July 14 until July 23 and served as the national championships in track and field for the United States. The Men's Marathon Trials were held May 7 in Pittsburgh, Pennsylvania. Maurice Greene, who won the 100 meter trial, and Michael Johnson, who won the 400 meter trial and was the defending 200 meter gold medallist, both pulled hamstrings in the 200 meter final. Neither qualified in that event.
