Date: Sept. 27, 2026 Participant: Jason Acosta #25786 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Fades Into a Gritty Finish Jason Acosta covered the half marathon in 1:48:28, an 8:16 min/mile pace. He opened briskly, clicking off his first two miles at 7:46 pace, then settled into a steady 7:508:00 rhythm through mile nine. The closing miles told a different story: mile 11 slowed to 9:27, and the final stretch held in the high 8:40s, making those opening two miles his fastest stretch of the day by a wide margin. That early speed came as Jason passed through Boulder, sitting over 5,000 feet above sea level. His pace through miles 9 and 10 carried him past the lululemon Power-Up Zone near mile 9.5, before the late-race climb toward the finish on the Pearl Street Mall took its toll. A touch more discipline over those opening miles could leave more in reserve for the closing stretch.
