Date: Sept. 27, 2026 Participant: Qingyu Zhou #26181 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Start Gives Way to a Hard-Fought Closing Stretch Qingyu Zhou finished the half marathon in 2:41:05. Her opening two miles were her fastest of the race, clicking off in roughly 11:22 per mile, before the pace eased through the middle miles. The slowest mile came at mile 9, at 13:23, before she settled back into the 12:40s-13:10 range to the finish, closing with a 12:41 final mile. Mile 9 fell just before the lululemon Power-Up Zone, situated around mile 9.5 on the half marathon course - a fitting spot for her toughest stretch before finding a more even rhythm to the Pearl Street Mall finish. Given Boulder's elevation above 5,000 feet, holding pace within a tight band over the second half is a solid execution note, and a touch more even pacing through miles 7-9 could be worth targeting in a future race.
