Date: Sept. 27, 2026 Participant: Sean Mcgivern #20329 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Gives Way to a Hard-Fought Finish Sean Mcgivern finished the half marathon in 2:14:04, an average pace of 10:14 per mile across the field of 7,223. Mcgivern's opening six miles were the highlight, holding between 8:32 and 8:43 pace for a cumulative 51:52 at the 6-mile mark. From mile 7 on, per-mile splits lengthened steadily, with the pace easing into the 9s and 10s through mile 10 before slowing further over the final miles. That early consistency came at altitude, in a city sitting above 5,000 feet, and it carried him through the lululemon Power-Up Zone near mile 9.5 before the closing stretch took its toll.
