Steady Pacing Powers a Strong 10K Finish Ellie Heiser completed the 2026 Boulderthon 10K in 56:52, holding a consistent pace across the distance and finishing with an overall effort well within the field of 3,071 participants in Boulder. Her mile splits stayed remarkably even through the first four miles, hovering between 9:09 and 9:30, before she found another gear at mile five, clocking her fastest mile of the race at 8:27. That surge marked the clear high point of her race, showing strong closing strength even as the pace eased slightly in the final mile. Finishing at altitude in Boulder, which sits above 5,000 feet, Heiser's ability to negotiate the distance with such consistency reflects well on her pacing strategy. Building on that final-mile speed could be a good focus for future 10K efforts.
