Date: Sept. 27, 2026 Participant: Jackson O'Hara #22280 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Sub-Seventy Split Sharpens a Strong Boulder Return Jackson O'Hara ran 1:10:34 to finish 7th overall and 7th among men in the 2026 Boulderthon Half Marathon, out of a field of 7,223. That's a clear step up from his 2025 result here, when he crossed in 1:14:47 for 13th overall more than four minutes faster this time. His race was built on an efficient front half: miles 1 through 6 came in a combined 31:18, a 5:13-per-mile pace that carried him into the race's top five. A brief dip through miles 7-8, peaking near 5:49, coincided with the approach to the lululemon Power-Up Zone around mile 9.5, before he steadied again, closing miles 12-13 at 5:13 and 5:19. With this year's half course cutting net elevation gain nearly in half, from 384 to 203 feet, that pacing pattern reflects well on his execution across Boulder's mile-high terrain.
