Date: Sept. 27, 2026 Participant: Isaac Hundley #12144 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Gives Way to a Hard-Fought Finish Isaac Hundley completed the marathon in 4:05:17. Through the first 17 miles he ran a tight band of 7:28 to 7:55 per mile, holding a cumulative pace near 7:40 for most of that stretch before the effort cost him over the back half, with mile splits stretching past 12, 13 and even 16 minutes in the 21-25 range. That opening 17-mile stretch was the clear highlight, sustained steadily despite Boulder's elevation above 5,000 feet. The fade coincided with the marathon's climb toward the lululemon Power-Up Zone near mile 22.5, where his pace had already slipped into the 13-15 minute range. Tightening the effort held through miles 18-20, where pace first began to drift from 7:57 to 8:15, could help preserve more of that early rhythm deeper into future races.
