Date: Sept. 27, 2026 Participant: Aiden Umina #25933 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pacing Anchors a Strong Finish Aiden Umina crossed the half marathon in 1:38:58, finishing 320th overall and 260th among men out of the field of 7,223. He also placed 35th in the men's 20-24 division. Umina's mile splits held tightly in the 7:20s-7:30s through the first ten miles, a consistent effort at Boulder's altitude of over 5,000 feet. A dip to 7:56 at mile 8 and 7:55 at mile 11 briefly slowed his rhythm, but he answered with the race's strongest stretch over the final two miles, splitting 7:21 and 7:10 to close out the course on the Pearl Street Mall. That late surge dropped his overall place from 309th to 243rd in the closing mile, a clean finish to build on.
