Date: Sept. 27, 2026 Participant: Sean Stewart #21106 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Powers a Top-Tier Half Finish Sean Stewart finished the 2026 Boulderthon Half Marathon in 1:27:45, an average of 6:41 per mile, placing 104th overall and 92nd among men in a field of 7,223. He returns after a strong showing in the 2024 Boulderthon 10K, where he placed 10th overall in 38:07. Stewart's race stayed remarkably even through the opening six miles, holding between 6:26 and 6:41 per mile before a brief dip to 7:05 and 7:01 in miles seven and eight. He answered with a strong close, dropping to 6:25 in mile twelve and 6:35 in the final mile to finish. That opening six-mile stretch, covering 39:26 at roughly a 6:34 pace, stood as his fastest sustained running of the day - notable given Boulder's elevation above 5,000 feet.
