Date: Sept. 27, 2026 Participant: Tom Harkness #20730 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Closing Kick Seals a Top-Tier Half Finish Tom Harkness crossed the line in 1:41:30, placing 407th overall and 323rd among men out of the field of 7,223. His pacing stayed remarkably even through the first six miles, hovering between 7:41 and 7:52 per mile, before a brief dip to 8:14 at mile eight. He answered immediately, settling back into rhythm through miles nine and ten. The standout stretch came in the final two miles, where Harkness ran 7:27 and 7:19 his fastest mile of the race to close with a negative split. That finishing surge came on a 2026 half marathon course redesigned to cut net elevation gain nearly in half, from 384 feet to 203 feet, a notable adjustment given Boulder's elevation above 5,000 feet.
