Felix qualified for the 2008 Summer Olympics at the 2008 Olympic trials by winning the 200 meters sprint in 21.82 seconds, but narrowly missed qualifying for the 100 meters sprint. In the Olympic 200 meter final, despite running her season's best time in the 200 meters at 21.93 seconds, Felix again finished second to Campbell, who ran 21.74 seconds, the best time of the decade, to win the gold medal. After her second loss to Campbell, Felix once again succumbed to tears. Felix avenged her loss by running in the 4 × 400 meters relay as a member of the U.S. women's team, helping the team finish first, giving Felix her first Olympic gold medal.
