Steady Pace, Strong Finish Through Boulder Clayton Marrs completed the 2026 Boulderthon Half Marathon in 1:33:26, an average pace of 7:07 per mile. His finish placed him in the top 10% of the field. Marrs ran a disciplined race, holding within a tight 6:567:00 per-mile band through the first ten miles before a natural late-race easing brought his overall pace to 7:07. His strongest stretch came in the opening 6 miles, covered in 41:38 at a 6:56 pace, showing solid control early. The final mile, run in 7:08, mirrored his overall average almost exactly a sign of a well-managed effort from start to finish through downtown Boulder, a city sitting above 5,000 feet of elevation.
