Date: Sept. 27, 2026 Participant: Thomas Gammelvind #22903 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing Capped by a Strong Closing Mile Thomas Gammelvind completed the half marathon in 1:50:02, an average pace of 8:24 per mile. His mile splits held in a tight band through the middle miles, mostly between 8:13 and 8:47, before he closed with his fastest full mile of the race, a 7:52 in the final mile. That closing surge brought him down Pearl Street Mall in downtown Boulder, a finish shared by every distance in the race, capping a well-controlled effort at over 5,000 feet of elevation. The tightening in his final mile, after miles in the high 8:30s to 8:40s range, points to well-managed pacing through the back half rather than a fade a pattern worth noting for future half marathons.
