Date: Sept. 27, 2026 Participant: Kari Chapman #30553 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Pace Through Five Miles Before a Late Fade Kari Chapman finished the 10K in 58:40 (9:27/mile). Her opening miles held tight between 9:09 and 9:19, and she found her best rhythm in mile five, clicking off 8:53the fastest mile of her race. That effort came at a cost, though, as the final mile slowed to 10:48, pulling her overall pace back up before the finish. Chapman's race unfolded entirely at altitude, with Boulder sitting more than 5,000 feet above sea level, and she closed out her 10K on the Pearl Street Mall in downtown Boulder. Her final mile offers a spot to consider pacing reserves for the closing stretch, a small adjustment that could help her carry that mile-five strength all the way to the line next time.
