Date: Sept. 27, 2026 Participant: Rachel Moser #11938 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong First Half Fuels a Steady Marathon Finish Rachel Moser completed the 2026 Boulderthon Marathon in 4:09:19, finishing 507th overall out of 3,305 in the field and 110th among women. She ran the first half in 1:56:45, holding a tight band between 8:39 and 9:20 per mile, with her fastest mile coming at mile 11 (8:39). The back half slowed to a 10:07 average mile pace, with miles 21-23 dipping toward 11:05, before a final push brought her home. That opening 13.1-mile stretch was the standout segment of the race remarkably even paced across Boulder County backroads before the course turns toward the lululemon Power-Up Zone near mile 22.5, where her pace had eased into the 10:00-11:00 range. Racing at Boulder's altitude of over 5,000 feet, Moser's disciplined early pacing set up a solid overall performance.
