Date: Sept. 27, 2026 Participant: David Welch #11028 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fastest Boulderthon Marathon Yet David Welch finished the 2026 Boulderthon Marathon in 4:38:51, his quickest of three appearances at this race, well ahead of his 5:05:17 in 2023 and 5:30:46 in 2024. He opened aggressively, covering the first four miles in just over 33 minutes, then settled into a steady 9:109:50 per mile rhythm through the middle miles before easing in the closing stretch, finishing with a 10:38 per mile overall pace. His opening four miles stood out as the strongest stretch of the race, holding sub-8:30 pace while the field was still tightly packed. Around mile 22, near the course's lululemon Power-Up Zone, his pace eased into the 14-minute range before he tightened things up again for the final mile a solid showing given Boulder's altitude above 5,000 feet.
