Even Pacing, Fast Finish Adam Brennan crossed the line in 1:39:33, good for 337th overall and 272nd among men in a field of 7,223. His overall pace of 7:35 per mile reflected a race built on control: miles 1 through 10 held in a tight 7:227:44 band, showing little variance across two-thirds of the course. The final three miles brought the race's sharpest gear change, with miles 12 and 13 clocking 7:03 and 7:01his fastest sustained running of the day and a clear surge through the closing stretch into downtown Boulder. The 2026 half marathon course carries nearly 50% less net elevation gain than in prior years, a shift that pairs with Boulder's altitude above 5,000 feet as useful context for a race run at this pace and consistency.
