Date: Sept. 27, 2026 Participant: James Munsell #12172 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Carries Through a Tough Back Half James Munsell finished the 2026 Boulderthon Marathon in 4:05:18, averaging 9:21 per mile across the 26.2-mile course. James ran his first 8 miles between 8:00 and 8:32 per mile, holding a tight, consistent rhythm through the early miles. Miles 9 through 18 settled into the 8:209:40 range, still steady work through the middle of the race. The strongest stretch came from mile 10 to mile 17, where he held between 7:57 and 8:38 per mile, his most efficient sustained running of the day. The final 10K slowed into the 10:3012:13 range as fatigue built, though he closed with a 10:39 mile 26. Given the marathon's route out past Boulder Reservoir and along Boulder County backroads before finishing on the Pearl Street Mall, and Boulder's elevation above 5,000 feet, the steady front-half execution stands out as the clearest strength of the race.
