Fast Start Carries a Steady Half Marathon Arthur Chan finished the half marathon in 1:49:56, an average pace of 8:23 per mile. He opened strong, holding paces between 7:55 and 8:24 through the first eight miles, before easing to 9:30 and 9:13 over miles nine and eleven. He rallied late, closing the final mile at an 8:31 pace to bring the race home. His quickest full-mile stretch came right out of the gate, an opening mile at 7:55, set against Boulder's elevation above 5,000 feet. That early pace came on the 2026 half marathon course, whose net elevation gain was cut by nearly 50 percent, a change that lines up well with the kind of brisk start Chan put together before settling into the race's second half.
