Steady Effort Builds to a Strong Closing Mile James Perez completed the 2026 Boulderthon 10K in 1:39:07. His race unfolded in two distinct halves: an opening mile at 15:17, a middle stretch that dipped to a 17:08 third mile, then a rebound through miles four and five before the pace eased again to the finish. The strongest stretch came in mile five, covered in 14:37, his fastest mile of the day and a clear high point in an otherwise fluctuating effort. Racing across a 10K course in Boulder, which sits above 5,000 feet of elevation, adds a layer of difficulty to any pacing plan. Given that context, Perez's ability to produce a sub-15-minute mile late in the race speaks well of his conditioning, and it's a strong note to build from for pacing consistency in future starts.
