Date: Sept. 27, 2026 Participant: Daniel Aguilera #11805 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Opening Miles Give Way to a Grinding Second Half Daniel Aguilera covered the Boulderthon Marathon in 4:37:34. He opened fast, holding sub-7:55 pace through the first six miles, then eased through the middle miles before a pronounced slowdown between miles 17 and 21, where per-mile splits climbed into the 11-to-18-minute range. He steadied in the closing miles, trimming his pace back toward 10 minutes per mile to close out the race. His best stretch came early: miles 1 through 6 averaged roughly 7:48 per mile, the fastest sustained running of his day. That opening effort came at altitude, with Boulder sitting above 5,000 feet. His rough patch through miles 21-22 carried him toward the lululemon Power-Up Zone near mile 22.5, after which he found firmer footing for the stretch into downtown Boulder's Pearl Street Mall finish.
