Date: Sept. 27, 2026 Participant: Diana Harper #31518 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start Fades Late in Steady 10K Effort Diana Harper completed the 2026 Boulderthon 10K in 1:29:20, an overall pace of 14:24 per mile. She opened with her fastest mile of the race at 11:26, then eased through the middle miles before slowing further over the closing stretch. Running at over 5,000 feet of elevation in Boulder, Harper's pace climbed steadily from that opening mile through mile five, settling into a more moderate rhythm before the finish on the Pearl Street Mall. Tightening the middle miles closer to that early tempo could help even out the effort in a future race.
