Date: Sept. 27, 2026 Participant: Shelby Wiseman #32740 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Early Pace Fades Late in Steady 10K Effort Shelby Wiseman covered the 10K in 53:50, an 8:41 per mile pace, finishing among a field of 3,071. Her race opened briskly, with back-to-back miles at 8:08 and 8:07, before a mile 4 dip to 9:01 slowed the cumulative pace slightly. She answered with a strong rebound in mile 5, clocking 8:13, before easing off over the final stretch to the Pearl Street Mall finish. Those opening two miles stand out as the fastest sustained stretch of the day, holding just over 8:07 per mile. Given that Boulder sits above 5,000 feet, sustaining that pace through the early miles reflects solid pacing discipline before the closing miles took their toll.
