Date: Sept. 27, 2026 Participant: Ben Kooiman #27876 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Through Altitude, Strong Kick in Final Miles Ben Kooiman finished the half marathon in 1:28:46, holding a remarkably consistent pace across the field of 7,223 participants. His mile splits stayed within a tight 6:317:00 range throughout, with cumulative pace never drifting far from 6:466:50 min/mile from start to finisha sign of even effort management across the full 13.1 miles. His strongest stretch came late, clocking a 6:31 split in mile 12, his fastest full mile of the race, as he closed with a final mile pace of 6:46. That surge came just after passing through the lululemon Power-Up Zone near mile 9.5, and reflects well-managed energy given Boulder's elevation above 5,000 feet. A slight easing of pace could be explored in miles 68 for an even stronger finishing kick.
