Date: Sept. 27, 2026 Participant: Tyler Phillips #13169 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Opening Miles Give Way to a Grinding Finish Tyler Phillips completed the 2026 Boulderthon Marathon in 4:38:26, an overall pace of 10:37 per mile. He moved through the opening miles briskly, covering the first 13.1 miles in 1:56:15 an 8:52 per mile average before pace gradually eased through the high 9-minute range into the high teens of the course. The back third told a different story, with per-mile splits climbing into the 1215 minute range from mile 18 onward as the effort of the day accumulated. That opening half-marathon stretch, held near 8:52 pace at over 5,000 feet of altitude, stands as the highlight of the race. The fade coincided closely with the marathon's lululemon Power-Up Zone near mile 22.5, right where his 22nd mile slowed to 13:51. Phillips closed out the effort on the Pearl Street Mall in downtown Boulder, a finish worth building on for pacing the second half more evenly next time.
