Date: Sept. 27, 2026 Participant: Hayden Humphrey #20598 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Negative Splits Power a Strong Closing Kick Hayden Humphrey finished the half marathon in 1:49:45, an 8:22/mile pace. His early miles held in the high-8:00s to 9:00 range, then tightened through the middle third before a sharp surge over the final two miles 7:31 for mile 12 and 7:46 for mile 13 the fastest sustained stretch of his race and enough to pull his overall average down meaningfully by the finish. That late charge came after passing the lululemon Power-Up Zone near mile 9.5, where he was clicking off 8:16 pace, still well above 5,000 feet of Boulder altitude. With his back half clearly stronger than his front, an even pacing plan that borrows some of that closing speed for the early miles could make for an even smoother race next time.
