Rock-Solid Early Pace Anchors a Hard-Earned Finish Katie Chapman finished the marathon in 4:21:05, an overall pace of 9:57 per mile. Her race was built on a remarkably even first half: from mile 1 through mile 14, she held between 8:34 and 9:08 pace, never wavering more than half a minute mile to mile. That opening stretch stands as the clear highlight of her day. The back half told a different story, with pace easing steadily from mile 15 onward as fatigue set in, before she rallied to close the final mile at 9:27. Boulder sits above 5,000 feet, a backdrop to any effort on these roads. The marathon route winds out past the Boulder Reservoir and through county backroads before returning to finish on the Pearl Street Mall. Her miles 22 and 23, run at 14:54 and 11:36 respectively, fell right around where the course's lululemon Power-Up Zone sits near mile 22.5.
