Jimmy Watkins, of the United States, competes during a track cycling men's sprint event, during the 2012 Summer Olympics, Saturday, Aug. 4, 2012, in London. No wonder Watkins is a fast sprinter. He's used to running up slopes with a hose to extinguish fires. The powerfully built Watkins, a 29-year-old firefighter from Bakersfield, Calif., can already be proud of his achievements at the Olympic Velodrome. On Sunday, Aug. 5, 2012, he will compete in the quarterfinals of the sprint tournament, track cycling's blue-ribbon event. (AP Photo/Matt Rourke)
