Katie Grimes put the hammer down on the final lap of the women’s 10km on Friday morning at U.S. Open Water Nationals, claiming victory and a spot at the 2023 World Championships.
After several different athletes took turns at the front of the race throughout, Grimes’ Sandpipers of Nevada teammate Claire Weinstein held the lead early on during the last of five laps of the race, with a group containing Mariah Denigan, Kensey McMahon, Ashley Twichell, Maria De Valdez and Grimes close behind.
Grimes moved to the front of the pack and managed to pull away, ultimately winning by 15 seconds to defend her national title and earn a spot at the World Championships in a time of 1:58:08.
After Weinstein and Denigan had a photo finish in the race for second, the nod ultimately went to Denigan, who is listed with a time of 1:58:23, one second clear of Weinstein.
Twichell, a 33-year-old veteran and Tokyo Olympian in open water, placed fourth in 1:58:25, while De Valdez (1:59:06) was fifth and McMahon sixth (1:59:09).
