Date: Sept. 27, 2026 Participant: Kirsten Mullikin #22524 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Effort Carries Her Through Boulder's Half Kirsten Mullikin finished the 2026 Boulderthon Half Marathon in 2:19:18, holding a consistent effort across the field of 7,223. Her opening mile came in at 9:48, and she stayed within range of that pace through the first 9 miles, crossing the 9-mile mark with an elapsed pace of 10:20 min/mile. The middle-to-late miles brought a gradual pace shift, with mile 10 slowing to 11:56, before she settled into a strong closing stretch, covering miles 11 through 13 at a steadier clip to finish just off her mid-race pace. Miles 1 through 6 stood out as Mullikin's most efficient stretch, holding between 9:48 and 10:31 per mile before the course's back half brought more variation. Boulder's elevation, sitting above 5,000 feet, adds a layer of difficulty to any pacing plan, and her ability to hold form into the final miles reflects well on her closing strength.
