Date: Sept. 27, 2026 Participant: William Anteliz #40106 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Second Mile Fuels Solid 5K Finish William Anteliz completed the 5K in 27:37, an 8:54 per-mile pace. He opened with an 8:53 first mile, surged to a 7:53 second mile, then eased to a 9:40 close, finishing 265th among men. That middle mile stood as the race's standout stretch, nearly a minute faster than his opening pace and the quickest segment of his day. Running at Boulder's altitude of over 5,000 feet, holding that surge before settling into the final mile reflects a race shaped by an early build and a controlled finish.
