Date: Sept. 27, 2026 Participant: Grant Rahja #27735 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Fades Late but Finish Holds Firm Grant closed the half marathon in 1:39:25, placing 330th overall and 268th among men in the field of 7,223. That marks a step back from his 2024 Boulderthon half marathon, where he ran 1:30:13 at a 6:53/mile pace. The race unfolded in two distinct phases: a strong opening stretch through miles 1-5, held at a tight 7:13-7:18/mile pace, followed by a gradual fade as fatigue set in. That early five-mile stretch stands as the fastest sustained running of his day. The middle miles slipped steadily, bottoming out at an 8:33 mile 11 before he rallied with a 7:30 mile 12. Passing through the lululemon Power-Up Zone near mile 9.5, he was already trending slower, having dropped to a 7:56 pace by mile 10 amid Boulder's mile-high altitude.
