Whitney ran a new career best of 50.29 seconds in the 400m at the 2021 Olympic Trials, good enough for fifth place and a spot representing the United States on the 4 × 400 m relay team for the 2021 Tokyo Olympics.

High school
Her 100 meters time also sets the national high school record as recognized by Track and Field News, though it will not be recognized by the NFHS as the USATF Junior Championships are not a high school competition. When published (the approval process by the magazine), the 200 meter record will be notated as a "low altitude" record by T&FN. Allyson Felix did run a faster 200 meters 22.11 at altitude in Mexico City before graduating from Los Angeles Baptist High School in 2003. Olympic gold medalist Felix is just one of the who's who of Olympians Whitney surpassed with the various records. Also on the list, the World Youth best in the 100 was held by Chandra Cheeseborough, the 200 best was held by Marion Jones, and the high school 100m record was held by Angela Williams.

At the time of her performance, her 200-meter time ranked her as the #8 time of the year against all women of any age, her 100m ranked #17.

While still a sophomore at East Ridge High School in Clermont, Florida, she was the 2014 Florida state champion in both events. As a youth athlete, Whitney was a star before reaching high school. In 2012, she set the American age 14 records in both the 100m and 200m in similar fashion, a day apart, destroying the youth records of future Olympic gold medalist, Sanya Richards. She trains with an elite group of athletes which includes Olympic gold medalist Justin Gatlin called Star Athletics coached by Olympic gold medalist Dennis Mitchell. She was Track and Field News "High School Athlete of the Year" in 2014.
