Date: Sept. 27, 2026 Participant: Karson Knuth #21517 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Carries Steady Half Marathon Effort Karson Knuth finished the 2026 Boulderthon Half Marathon in 2:15:15, holding a 10:19 min/mile pace across the 13.1-mile course through downtown Boulder. Knuth's early miles were her strongest, clicking off the first six miles between 9:18 and 9:39 min/mile pace, keeping her elapsed pace under 9:30 min/mile through the 6-mile mark. The second half of the race saw a natural settling, with per-mile splits gradually easing into the 10:25-11:53 min/mile range as the course wore on. Given the altitude in Boulder, sitting above 5,000 feet, that early speed reflects solid pacing instincts. A slightly more even effort in the middle miles could help preserve more of that early rhythm through the finish next time out.
