Mu, who hails from Trenton, New Jersey, was named the National Women’s Track Athlete of the Year. The sensational freshman ended the season in style at the 2021 NCAA Division I Outdoor Track & Field Championships, lowering her own collegiate record in the 400 to 49.57 – while matching the largest margin of victory in meet history – and split 48.85 on the anchor leg of Texas A&M’s 4×400 relay team that also set a collegiate record of 3:22.34. Mu ended the outdoor season with three collegiate records – add the 800 at 1:57.73, for good measure – and five individual all-time top-10 marks – four in the 400 alone (No. 1, No. 2, No. 5, No. 8).
