Date: Sept. 27, 2026 Participant: Haylie Lopez #27871 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Early Pace Anchors a Determined Half Marathon Finish Haylie Lopez completed the 2026 Boulderthon Half Marathon in 2:19:27, holding a consistent 10:0910:21 min/mile pace through the first ten miles before easing through the closing stretch. Miles one through four were the highlight, clocking between 10:09 and 10:14 min/mile the most even stretch of the race. From there, pace gradually settled into the 10:30s and 11:00s over the final miles, a natural shift given the demands of covering 13.1 miles at Boulder's altitude, where the city sits above 5,000 feet. Lopez's race finishes on the historic Pearl Street Mall in downtown Boulder, capping a well-managed effort built on a strong front half.
