Date: Sept. 27, 2026 Participant: Bradley Kuper #12807 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Gives Way to a Hard-Fought Back Half Bradley Kuper finished the 2026 Boulderthon Marathon in 4:26:56. His race showed two distinct phases: a tightly controlled opening 15 miles holding between 8:08 and 9:01 per mile, then a steady climb in effort from miles 16 through 26 as pace settled into the 12:2914:14 range. The first 15 miles stand out as his strongest stretch, run at a consistent sub-8:30 average pace before the final third of the course demanded more from him. Boulder's elevation, over 5,000 feet, sits behind every mile of this race, and Kuper's disciplined opening miles reflect that adjustment well. He would have passed through the lululemon Power-Up Zone near mile 22.5 while working through his 12:52 split, a useful lift points as the marathon's closing miles asked the most of his legs before the finish on the Pearl Street Mall.
