Date: Sept. 27, 2026 Participant: Matthieu Filliat #24386 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Early Pace Fuels Strong Half Marathon Finish Matthieu Filliat finished the 2026 Boulderthon Half Marathon in 1:31:38, an average pace of 6:59 per mile, placing 160th overall and 135th among men in a field of 7,223. Filliat ran a controlled and consistent race through the first nine miles, holding between 6:33 and 7:00 per mile and reaching the halfway point in 33:54. That opening stretch stands out as his strongest mile-plus segment, showing tight pacing discipline over distance. The pace eased slightly from mile 10 onward, dipping to 7:41 for mile 11 before he rallied over the final two miles to close in 7:04. With the finish landing on the Pearl Street Mall in downtown Boulder, sitting above 5,000 feet, Filliat's ability to hold sub-7:00 pacing for most of the race reflects a well-managed effort at altitude.
