Not only did Allie Ostrander dominate the competition at the Deseret News 10K in Salt Lake City, Utah, she crushed the course record.

The professional runner for Oiselle conquered the 6.2-mile course in a scorching 30 minutes, 50 seconds, averaging a pace of 4:58 per mile on the net downhill course.

Although the course featured a gradual 600-foot elevation drop from start to finish, Ostrander still put together a performance for the ages at altitude, leading wire-to-wire.

The 29-year-old blasted through the 5K mark in 15:04 — a personal best regardless of conditions — en route to a 10K PB, marking her first time going sub-31.

The mixed-gender race format also allowed Ostrander to battle with male competitors, finishing 11th overall.

“I love duking it out with anyone that’s in the race,” Ostrander told Deseret News. “It’s so fun that we all get to be on the road at the same time. In this race for example, we were going back and forth. Someone would pass me, I’d pass someone. It’s just super engaging and fun.”

The Kenai Central graduate is now the fastest woman in race history, slicing 23 seconds off the course record (31:13) set by Grayson Murphy in 2021.

It also marks the fastest 10K time ever by an Alaskan woman, regardless of conditions.

Utah’s Lexie Thompson (32:16) and Hannah Branch (33:05) rounded out the top-3.

The race is Ostrander’s third in as many weekends, coming just six days after placing runner-up at the U.S. 8K Championships — her best finish at a U.S. Championship — and 13 days after a fourth-place showing at the U.S. 6K Championships.

“I wanted to kind of see what I could do stacking a bunch of races and managed to make it through unscathed, and am pretty happy with the results,” Ostrander told Deseret News.

This marks the second course record Ostrander has set this year, after winning the Statesman Cap10K in 32:45 in Austin, Texas.
