Bianca Knight

Knight was born on January 2, 1989, in Pearl, Mississippi. She began competing in track and field at 11 years old. She attended Pearl High School, but was kicked off the school track and field team after eighth grade. This came after her times in the summer competing at the USATF Junior Olympics being better than her high school times. Pearl High School coaches believed that Knight was not trying in high school, however Knight argued that the USATF competition brought out the best in her.

Knight transferred to Ridgeland High School in Ridgeland, Mississippi, winning 15 individual state titles. Including relays, Knight's 23 state titles puts her as one of the most decorated track and field athletes in Mississippi high school history. She was named 2006 female Gatorade Athlete of the Year in track and field in. She is the first Mississippi native to win a Gatorade Athlete of the Year award.

On Feb. 17, 2007, Knight set the national indoor record in the 200 at the Simplot Games in Pocatello, Idaho with a time of 22.97 seconds. The record stood until February 2023, when Mia Brahe-Pedersen ran a 22.89 at the Don Kilby Invitational in Albuquerque, New Mexico.

Knight attended the University of Texas, choosing the Longhorns over the University of Kentucky, Louisiana State University and the University of Southern California. In her lone year for the Longhorns, Knight won the 2008 indoor NCAA 200-meter championship in a collegiate-record time of 22.40. The record stood for 12 years, with Kentucky sprinter Abby Steiner breaking the record with a time of 22.38 in 2021.

After one year competing for Texas, Knight became one of the first athletes in the U.S. to accept a professional contract after their freshman year.

Knight signed with Adidas after turning professional following her freshman indoor campaign. She finished fifth at the 2008 U.S. Olympic Trials in the 200 with a time of 22.25 seconds.

Knight retired from track and field in 2016 to focus on her family. She has two sons.

Knight founded the Bianca Knight Foundation, which focuses on providing resources to young track and field athletes. In 2021, Knight launched the BKTrackstars app, which offers advice and workout plans for track athletes.
