Steady Early Pace Fuels Strong Marathon Finish Mason Comer completed the 2026 Boulderthon Marathon in 4:32:23, an average pace of 10:23 per mile. Comer ran the first ten miles between 9:05 and 9:33 per mile, holding a tight, even rhythm through the race's early stages. That consistency carried through the half-marathon mark, with his cumulative pace sitting at 9:16 per mile at mile 13. Miles 11 through 13 were his strongest stretch, clicking off at an 8:48-9:23 pace and pushing him to his best overall position of the race. The back half saw a natural easing, with miles 19 through 25 slowing into the 10:43-15:06 range before he closed with a 10:17 mile to the finish. Given Boulder's elevation above 5,000 feet, the steady first half stands out as the foundation for his overall time.
