Date: Sept. 27, 2026 Participant: Jack Nauseef #24751 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Finishing Kick Fuels Steady Half Marathon Jack Nauseef ran the 2026 Boulderthon Half Marathon in 1:51:36, holding a consistent 9:10-9:20 pace per mile through the race's first nine miles. From there, he shifted into a sustained drop, running mile ten in 7:58 and then reeling off 7:11, 6:42, and 6:24 miles to close out the final stretch a negative split that pulled his overall pace down to 8:31 per mile by the finish. That last four-mile surge, cutting nearly three minutes per mile off his early pace, stands as the clear highlight of his race. Given the redesigned 2026 half marathon course trims net elevation gain to roughly 203 feet, Nauseef's late-race acceleration through downtown Boulder and onto the Pearl Street Mall reflects strong control of effort across the second half.
