Date: Sept. 27, 2026 Participant: Alex Edmiston #13165 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Front Half Fades Late in Marathon Debut Alex Edmiston finished the 2026 Boulderthon Marathon in 4:38:04. He built a steady rhythm through the first 13 miles, holding between 8:50 and 9:15 per mile and reaching the half in roughly 1:56. That pace held firm through mile 18, but the back stretch of the race saw a marked slowdown, with per-mile splits climbing into the 12- to 16-minute range from mile 19 to the finish. The opening 13 miles stand as his strongest stretch of the day, run at a consistent sub-9:00 clip despite Boulder's elevation above 5,000 feet. Coming through the lululemon Power-Up Zone near mile 22.5, his pace had already eased into double digits, and he carried that steadier effort home to the finish on the Pearl Street Mall. A focus on maintaining more of that early rhythm into the final 10K could be a useful target for his next marathon.
