Steady Early Pace Gives Way to a Tough Final 10K Payton Kiser completed the marathon in 4:18:27, an average pace of 9:51 per mile across Boulder's 26.2-mile course at altitude. His race settled into a strong rhythm between miles 8 and 13, where he covered that stretch in just under 44 minutes, holding pace in the high 8:40s to high 8:50s per mile and running his most consistent segment of the day. That effort carried him through the halfway point with his placement improving steadily. The back half told a different story. From mile 19 onward, his per-mile splits climbed into the 10:30-13:48 range, with the largest slowdown arriving between miles 21 and 24. Kiser passed through the lululemon Power-Up Zone near mile 22.5 during this stretch, and finished strong over the final two miles, closing with a 10:57 split to reach the Pearl Street Mall.
