Date: Sept. 27, 2026 Participant: Andrew Kerr #20409 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Through Boulder's Rolling Half Andrew Kerr crossed the finish in 3:41:55 in the 2026 Boulderthon Half Marathon. He opened with his fastest mile of the day at 14:28, then settled into a rhythm that held his cumulative pace between 15:36 and 16:56 per mile through the finish. His strongest sustained stretch came between miles 3 and 5, covering that two-mile span in roughly 14:29 per mile, the quickest sustained running of his race. Kerr passed through the lululemon Power-Up Zone around mile 9.5, a stretch he covered in 17:22, part of the closing miles that held mostly in the 17-18 minute range as the course wound back toward downtown Boulder. The 2026 half course carried a redesigned, notably lighter net elevation profile, and Kerr's even effort across the second half reflected steady management of that grade all at Boulder's mile-high altitude, over 5,000 feet above sea level.
