Date: Sept. 27, 2026 Participant: James Beattie #10151 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Pace Carries Marathon Debut Through Boulder's Backroads James Beattie completed the Boulderthon Marathon in 4:19:18, averaging 9:53 per mile. His mile splits stayed remarkably consistent through the middle miles, holding between 9:24 and 10:05 from mile 9 through mile 20, before a tougher patch from miles 21-23 (10:59, 10:27, 10:25) as fatigue crept in. He answered strongly, though, closing with a 8:57 final mile his fastest of the race to finish with real momentum on the Pearl Street Mall. Miles 10 through 14 stood out as his strongest sustained stretch, five miles run between 9:17 and 9:49, tightening his overall pace after a slightly slower start through the first 9 miles. That mid-race surge, run out toward Boulder County's backroads and the reservoir, laid the foundation for the finish. Given Boulder's elevation above 5,000 feet, that closing kick was a strong signal of well-managed effort across the full 26.2 miles.
