Date: Sept. 27, 2026 Participant: Dylan Keeney #13100 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong First 17 Miles Precede a Tough Back Stretch Dylan Keeney finished the marathon in 4:37:45, an average pace of 10:36 per mile across the 26.2-mile course that finishes on the Pearl Street Mall in downtown Boulder, sitting above 5,000 feet of elevation. Keeney's race showed a clear two-part shape. Through the first 17 miles, he ran a steady, well-controlled pace of 9:14 per mile, holding that rhythm with little variation mile to mile. From mile 18 onward, his pace eased considerably, extending into the 12- to 14-minute range over the closing miles. That fade included the stretch around mile 22.5, where he passed through the lululemon Power-Up Zone while running roughly 13:47 per mile. Given the strength of the opening two-thirds of the race, working on sustaining that early rhythm deeper into the back half could be a useful focus for next time.
