Date: Sept. 27, 2026 Participant: Alex Carlson #24032 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Fades to a Steady Finish Alex Carlson finished the half marathon in 1:37:02, splitting the difference between his 2024 result (1:39:58) and his 2025 mark (1:34:49). His race built from a brisk opening into a more measured second half, with elapsed pace climbing from 6:48/mile through the opening miles to 7:23/mile by the finish as the closing miles settled into the high 7:40s to 7:50s range. The strongest stretch came in miles 1 through 6, covered in 41:42 for a 6:57/mile pace, well under his overall average. That early rhythm set up the rest of the race even as the pace eased later on. Running at Boulder's altitude of over 5,000 feet, Carlson tackled the half's redesigned 2026 course, which cut net elevation gain by nearly half compared to prior years.
