Date: Sept. 27, 2026 Participant: Sean Lemkey #32363 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Start, Steady Fade to a Solid Finish Sean Lemkey finished the 10K in 49:36, placing 157th overall and 111th among men in a field of 3,071. That result reflects a well-executed pacing effort through the opening miles of the race. Lemkey's fastest mile came early, covering mile two in 7:35, part of a strong first two miles that anchored his overall pace near 7:387:43 per mile through the race's first half. From there, his per-mile splits gradually lengthened, dipping to 8:13 by mile four before rebounding to 7:46 in mile five. The final mile came in slower, closing out the race at Boulder's elevation of over 5,000 feet a demanding backdrop for any distance. Overall, the race showed a runner capable of setting a fast pace out of the gate; building a bit more reserve for the closing miles could help sustain that opening speed in future 10Ks.
