Date: Sept. 27, 2026 Participant: Kate Concannon #24764 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Carries Strong Closing Mile Kate Concannon finished the 2026 Boulderthon Half Marathon in 1:39:11, placing 325th overall and 62nd among women in a field of 7,223 a result inside the top five percent of entrants. Her pace held remarkably even across the distance, hovering between 7:18 and 7:34 per mile for long stretches, with elapsed pace never drifting outside a 20-second band from start to finish. After a slight dip through miles 6 through 9, where splits eased into the high 7:30s and low 7:50s, Concannon closed with her fastest full mile since the race's opening stretch, covering mile 12 in 7:21 before finishing on the Pearl Street Mall. That surge, on a half marathon course redesigned this year to trim net elevation gain to roughly 203 feet, capped a well-controlled effort at Boulder's 5,000-plus-foot altitude.
