Date: Sept. 27, 2026 Participant: Caroline Colimore #26714 Race: 2026 Boulderthon Half Marathon Distance: 13.1 miles

Strong Negative Split Seals a Steady Half Caroline Colimore covered the Boulderthon half marathon in 2:02:51. Her pace climbed early, peaking near 10:09/mile by mile 3, before steadily dropping through the second half of the race. That downward cumulative trend never reversed, closing with an 8:19 final mile. The clearest strength came in the last four miles, from mile 9 to the finish, covered at an average pace of about 8:41/mile well under her overall race pace and the fastest sustained stretch of her day. That closing surge carried her onto the Pearl Street Mall in downtown Boulder, a fitting finish to a race run at altitude, with Boulder sitting over 5,000 feet above sea level.
