Date: Sept. 27, 2026 Participant: Eli Chapman #12142 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Fast Start Fuels a Long Marathon Grind Eli Chapman completed the 2026 Boulderthon Marathon in 5:11:32, an overall pace of 11:53 per mile over the 26.2-mile course. He opened quickly, covering the first three miles in 29:20 (9:47 per mile), and his best sustained running came from miles 6 through 13, where he averaged 9:41 per mile. From there his pace eased steadily through mile 20, then slowed further over the closing six miles as fatigue set in, carrying him to the finish on the Pearl Street Mall. The marathon's final stretch runs past the lululemon Power-Up Zone near mile 22.5, an area Chapman crossed with his elapsed pace at 11:14 per mile, just before the race's toughest closing miles took hold. At over 5,000 feet of elevation, Boulder's altitude adds its own demand to those late stages of the course.
