Date: Sept. 27, 2026 Participant: Arianna Kincaid #13410 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Holds Firm Before a Late-Race Fade Arianna Kincaid completed the 2026 Boulderthon Marathon in 4:02:04, an elapsed pace of 9:14 per mile. She opened strong, holding sub-9:00 pace through the first nine miles, with elapsed time at 1:18:44 for 8:44 per mile. The middle miles held near 9:00 per mile before the pace eased in the back half, elapsed pace climbing to 9:15 by mile 25. A strong closing mile 8:45 for mile 26 pulled her final average back down to 9:14 per mile at the finish. That opening stretch through mile 9 stands as the run's strongest mile-plus segment, sustained well above her overall average. Running that pace at Boulder's altitude of over 5,000 feet, on a course that heads out past Boulder Reservoir and along Boulder County backroads before finishing on the Pearl Street Mall, made for a well-managed effort from start to finish.
