Steady Early Pace Carries Through a Demanding Marathon Finish Luis Grajeda completed the 2026 Boulderthon Marathon in 6:50:04. He opened strong, covering the first four miles in roughly 11:37 pace, and held between 11:30 and 13:00 pace through halfway, reaching the 13-mile mark in 2:40:13. The middle miles gradually slowed, with pace easing past 14:00 by mile 20, then continuing to stretch through the 20s before settling in over the final miles to the finish on the Pearl Street Mall. His strongest mile-plus stretch came early: miles 1 through 4 averaged just over 11:30 pace, the fastest sustained running of his race. Grajeda finished the marathon in downtown Boulder, a course that also passes near Boulder Reservoir, at over 5,000 feet of elevation a factor for any distance runner tackling this event.
