Date: Sept. 27, 2026 Participant: William Cordonnier #41681 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Second Mile Fuels Top-10% Finish William Cordonnier crossed the line in 23:43, placing 184th overall out of the field of 2,677 and 142nd among men in the 5K. His race built momentum early, opening with a 7:34 first mile before surging to a 6:38 second mile, his fastest of the day. That effort pushed his overall pace under 7:10 per mile at the two-mile mark before a 8:39 closing mile brought him home. Given Boulder's elevation above 5,000 feet, that middle-mile surge stands out as the highlight of his race. With the final stretch finishing on the Pearl Street Mall, William has a strong foundation to build on for pacing the third mile more evenly in future races.
