Date: Sept. 27, 2026 Participant: Sierra Quintana #31386 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Consistent Pacing Anchors a Solid 10K Effort Sierra Quintana finished the 10K in 1:03:12, averaging 10:11 per mile among the 3,071-strong field in Boulder. Her early miles were remarkably even, clicking off in the 9:5110:06 range through the first four miles before she found her best rhythm of the day. Mile five was her standout stretch, dropping to 9:45 the fastest mile of her race before the pace eased to 11:22 over the final mile to the finish on the Pearl Street Mall. Running the course at over 5,000 feet of elevation, Quintana's steady first four miles reflect strong pacing discipline; building a touch more strength into that closing mile could help her carry her mid-race speed all the way home next time.
