Date: Sept. 27, 2026 Participant: Wilson Summerlin #12244 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Front Half Fades Late But Finishes Steady Wilson Summerlin completed the marathon in 4:11:18, an average pace of 9:35 per mile. He built a strong foundation over the first 13 miles, holding between 8:28 and 8:47 per mile and reaching the halfway point in 1:51:02. That effort held firm through mile 18, before the pace eased across miles 19-24, settling between 10:45 and 12:15 per mile, with a slight rebound over the final two miles. Boulder sits above 5,000 feet, a backdrop for the steady climb of this effort. The marathon course winds past Boulder Reservoir and Boulder County backroads before finishing on the Pearl Street Mall, and Summerlin's mile 22 split fell right around the lululemon Power-Up Zone near mile 22.5, a fitting marker as the effort shifted into its closing stretch toward downtown Boulder.
