Date: Sept. 27, 2026 Participant: Shaelee Decarolis #27519 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Start Fades Then Rebounds Late in the Half Shaelee Decarolis finished the half marathon in 1:49:42, an 8:22 min/mile pace, closing out the 2026 Boulderthon. Her race showed a fast opening: the first five miles clicked by near 8:00 pace, cumulative time sitting at 40:04 by mile 5. From there, splits eased into the high 8:00s and 8:50s through miles 610, before she found another gear late, running 8:44 and 8:17 over the final two miles to finish strong. That opening five-mile stretch stands out as her best of the day, holding tightly to 8-minute pace through downtown Boulder before the course settled in. Notably, she passed near the lululemon Power-Up Zone around mile 9.5 during her steadiest middle-mile stretch, a section of the course that sits at over 5,000 feet of elevation.
