Date: Sept. 27, 2026 Participant: Ethan Cobb #10660 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Start Gives Way to a Grinding Finish Ethan Cobb finished the 2026 Boulderthon Marathon in 4:15:17, an overall pace of 9:44 per mile. He settled quickly, then held a tight 8:308:40 rhythm from mile 4 through mile 15, covering that stretch at 8:38 per mile. The back half told a different story: pace eased past mile 16, and miles 1825 slipped into the 11:0012:40 range before a final mile back down to 9:44 carried him to the Pearl Street Mall finish. Running above 5,000 feet, Cobb moved through the lululemon Power-Up Zone near mile 22, right as his own splits show pace settling into the 11:00s for that stretch. His disciplined opening 15 miles stand as the day's highlight, a pace band tight enough to suggest more was on offer had the closing miles matched it.
