The Chainkeen2024 U.S. Olympic track and field trials begin Friday in Eugene, Oregon. The opening day features round one of the women’s 100 meters and sprinter Sha’Carri Richardson.

Richardson has the top qualifying time entering the 100 at 10.65 seconds. Tennessee’s Jacious Sears is second on the list with a time of 10.77 seconds and Twanisha Terry has the third best time at 10.83 seconds.

Sears’ 10.77 is the top time in the world this year.
