Fast Start Fades Late in Marathon Return Brian Mckenna finished the 2026 Boulderthon Marathon in 4:05:58. It's a step back from his 2023 result of 3:22:04, when he ran nearly a full 1:44 faster over the same distance. Through the first 15 miles this year, Mckenna was on a strong pace, covering that stretch in under 8:00/mile and holding under 2:00:00 elapsed at the midpoint region. Miles 1-7 were his standout stretch, averaging around 7:33/mile, well ahead of his eventual overall pace of 9:23/mile. After mile 15, the pace steadily eased, with miles 16-26 settling into the 9:18-13:16/mile range as the final third of the race took its toll. Mckenna's race unfolded at altitude, with Boulder sitting above 5,000 feet, a demanding backdrop for holding early pace across 26.2 miles.
