Date: Sept. 27, 2026 Participant: Jaxon Hall #12975 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fades Late in the Marathon Jaxon Hall finished the 2026 Boulderthon Marathon in 4:37:08, averaging 10:34 per mile. His first 14 miles were remarkably steady, running between 8:40 and 9:34 per mile, holding a consistent low-9:00s pace through halfway. From mile 15 onward, splits gradually lengthened, with miles 21 and 23 slowing to 14:16 and 14:18 respectively, before a modest rebound in the final mile at 11:00. The opening 14 miles stand out as his strongest one-mile-plus stretch, sustaining a pace nearly a minute faster than his overall average. Given the marathon route heads out past Boulder Reservoir before finishing on the Pearl Street Mall, Hall's steady first half set up a solid foundation, and the closing miles into downtown Boulder, at over 5,000 feet of elevation, offer a clear opportunity to build strength for an even stronger finish next time.
