Date: Sept. 27, 2026 Participant: Kirby Wolf #25864 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Late Surge Powers a Steady Half Marathon Kirby Wolf finished the half marathon in 1:49:15 (8:20/mile). After an opening mile at 9:02, he settled into a steady rhythm through the middle miles, holding between 8:02 and 8:46 pace from miles 2 through 11, before accelerating in the closing stretch. That finish was the clear highlight: miles 11 through 13 came in at roughly 7:24/mile, well under his overall average and the fastest sustained stretch of the race. That surge carried him near the course's lululemon Power-Up Zone at mile 9.5, where his pace had already begun tightening before the final push. Running the full distance at Boulder's altitude, over 5,000 feet, Wolf closed strong onto the Pearl Street Mall. If there's one thing to build on, it's carrying that late-race pace closer to the midpoint next time out.
