De'Hashia Tonnek "DeeDee" Trotter (born December 8, 1982, in Twentynine Palms, California) is an American athlete.

She specialized in both the 200m and 400m in track, and in her senior year, she also helped lead the 4 × 400 m relay team from her highschool to the Georgia State Championship.

[3] Trotter was mainly a basketball player in high school, and took up track-and-field as a second sport under the encouragement of those who saw her running on the court.

She earned a track-and-field scholarship to the University of Tennessee, and was forced to turn away from basketball and focus solely on running.

[4] In 2007, she finished first in the 400m at the US Track and Field Championships, with the fastest time in the world that year: 49.64 seconds, and afterwards stated that her victory "was like a dream".

She was running with a broken bone chip in her left leg, the result of an errant car door closing on her two months ago.

[4] Still, in 2010 during the Reebok Boston Indoor Games Trotter tripped near the beginning of the race, but was able to recover her stride and eventually place first in the 400m event despite the misstep.

After a thirteen-year career, Trotter waved farewell to the crowd at Hayward Field in Eugene, Oregon, after crossing the finish line of the 400m semifinals and not advancing to the finals.

[1] That year she also began a fundraising drive called Gifted Soles, which gathers shoes for the homeless population of Orlando.

[23] Trotter is the founder of Test Me I'm Clean, a charity dedicated to combating the abuse of steroids and other performance-enhancing drugs.

She also acts as the organization's spokesperson, traveling across the United States giving speeches and presentations to students about the importance of staying clean.

[4] Those that support the organization can identify themselves with a white and red rubber armband, which Trotter herself wore during her 2012 bronze medal race.

Trotter was inspired to found the charity in 2006, after overhearing a conversation on an airplane where the participants were convinced that all elite athletes were on steroids, which she took exception to.

[26] After this initial advocacy, Athens 4 × 400 m relay team member Crystal Cox, pleaded guilty to a doping violation in 2010, and was stripped of her gold medal.
