Date: Sept. 27, 2026 Participant: Colby Pearce #24192 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Nearly Nine Minutes Faster: A Strong Negative Split to Close Colby Pearce crossed the line in 1:37:31, finishing 280th overall and 228th among men in a field of 7,223. That result marks a significant jump from his 2025 Boulderthon half marathon, where he finished in 1:45:58 an improvement of roughly 8:27 this time around. Pearce's pacing stayed remarkably tight through the race, holding between 7:16 and 7:46 per mile for most of the distance. He found his strongest form over the final two miles, splitting 7:17 and then 7:09 his fastest mile of the day to close things out. That kind of finishing kick is well worth building on, perhaps by testing an even earlier surge in a future race. Running at Boulder's altitude of over 5,000 feet, and on a 2026 half marathon course redesigned to cut net elevation gain nearly in half, adds context to a well-paced effort.
