Date: Sept. 27, 2026 Participant: Carlyn Shapiro #27278 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Steady Pace Surge Carries Her Through the Back Half Carlyn Shapiro finished the Half Marathon in 1:55:26, an 8:48 min/mile average pace. Her race opened conservatively, with the first three miles ticking by at an 11:27 min/mile average, before she settled into a rhythm in the high 8:50s that carried through the middle miles. Her strongest stretch came late: from mile 8 to mile 13, she averaged 8:39 min/mile, steadily pulling her overall pace down mile after mile. That surge came right around the lululemon Power-Up Zone near mile 9.5, where she was clipping along at 8:53 min/mile. Given Boulder's elevation above 5,000 feet, that late push stands out as the highlight of her race a strong finish worth building on for pacing evenly from the start next time.
