Steady Front Half Carries a Boulder Marathon Finish Matthew Cox completed the Boulder Marathon in 3:58:41, finishing 7th in the men's 50-54 division. His race showed a clear two-part shape: a controlled, even first half through 13 miles at roughly 8:15 per mile, followed by a gradual fade as the back half wore on, with the final 10K slowing into the 10:00-11:46 per-mile range. The standout stretch came early miles 1 through 13, held within a tight 8:00-8:30 per-mile band, a pace built at altitude in a city sitting over 5,000 feet. That control set up the run through Boulder County backroads before the course turned back toward the Pearl Street Mall finish. The toughest mile came near the lululemon Power-Up Zone around mile 22.5, where his split slowed to 11:44, the low point of an otherwise disciplined effort.
