Date: Sept. 27, 2026 Participant: Aaron Kanter #11749 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Strong Early Pace Fades Over Boulder's Back Miles Aaron Kanter finished the marathon in 4:11:50, part of a field of 3,305. His race opened fast, covering the first 10 miles at an 8:00 min/mile pace, the strongest stretch of his day. From there, mile splits lengthened steadily passing 9:30 by mile 14, 10:19 by mile 18, and climbing past 12:00 through the mid-20s before a final mile closing under 12:00. Running at Boulder's altitude of over 5,000 feet, Kanter covered a course that heads out past the Boulder Reservoir and through county backroads before returning to finish on the Pearl Street Mall. The early ten miles show real strength; building a touch more even pacing into the back half could help him carry that opening speed further next time.
