Strong Early Pace Carries Half Marathon Effort Through the Finish Ryan Kaysen finished the 2026 Boulderthon Half Marathon in 1:42:43, an elapsed pace of 7:50 per mile. Kaysen opened briskly, covering the first mile in 7:08 and holding sub-7:20 pace through mile four before easing gradually as the race progressed. The middle miles brought a natural settling, with splits drifting into the 8:10-8:25 range between miles seven and eleven, before a final push saw miles twelve and thirteen tighten back to 7:51 and 7:53. The opening 6-mile stretch stood out as the strongest segment of the race, with cumulative pace never slower than 7:26 per mile through that point. Racing at Boulder's altitude of over 5,000 feet, Kaysen's ability to close with two of his fastest miles late in the race reflects a well-managed effort overall.
