Wilson’s indoor season started with a collegiate record in the 600m as her 1:25.16 effort broke the previous mark of 1:25.80 set by Athing Mu while at Texas A&M in 2021.
As Wilson raced in the 800m during the SEC Indoor, earning a silver medal, she watched Diggs break the American and collegiate 400m record with a 50.15 victory. Razorback Amber Anning broke Wilson’s Arkansas school record of 50.88 with a 50.68 performance in the SEC 400m.
During the NCAA Indoor 400m semifinal, Wilson nearly reclaimed the Arkansas school record with a 50.69 that led the field with Diggs second best at 50.79.
Occupying lane 5 in the final, with Diggs stationed in lane 6, Wilson trailed Diggs through 200m (23.17 to 23.56). On the second circuit of the track, Wilson passed Diggs on the backstretch and pulled away from the field through the curve. Wilson’s edge over Diggs on the second 200m of the race was 25.92 to 27.32.
With a drive to the finish line, Wilson became the first collegian to run under 50 seconds indoors. Her time of 49.48 became the American and collegian record while occupying the No. 2 position on the world all-time list.
The previous world record of 49.59 had lasted 41 years and within one month it was bettered twice this indoor season. Femke Bol of the Netherlands broke the world record with a 49.25 in February.
