Date: Sept. 27, 2026 Participant: Kaelin Salazar #10292 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Even Opening Miles Give Way to a Hard-Fought Back Half Kaelin Salazar finished the Boulderthon Marathon in 4:25:35 over the 26.2-mile course that ends on the Pearl Street Mall. His race split into two distinct phases: a steady, controlled first half holding close to 8:258:40 per mile, followed by a clear slowdown that began around mile 12 and deepened sharply between miles 18 and 21, where per-mile pace climbed into the mid-teens and then past 18 minutes before leveling off again toward the finish. The strongest stretch of the day came in the opening seven miles, covered in 59:12 for an average of roughly 8:27 per mile the fastest sustained running of his race. That quick start came at Boulder's altitude of over 5,000 feet, and by the time he passed the lululemon Power-Up Zone near mile 22.5, his overall pace had eased into the 11-minute range. Building a slightly more conservative opening could help him carry that early rhythm further into the back half next time.
