Date: Sept. 27, 2026 Participant: Rachel Miles #30351 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Start Fades Late in Aurora Runner's 10K Rachel Miles finished the 2026 Boulderthon 10K in 1:03:44, an elapsed pace of 10:16 per mile. Miles opened strong, covering the first two miles in 18:34 with a second-mile split of 9:03, her fastest mile of the race. From there, her cumulative pace eased steadily, drifting from 9:17 at mile two to 10:19 by the finish as each successive mile ticked slower. The race played out at altitude, with Boulder sitting above 5,000 feet, a backdrop for the gradual pace shift across the back half of the course. Miles's early miles show a runner capable of quick starts; building a bit more evenness into the middle miles could help her sustain that opening rhythm through to the finish.
