Date: Sept. 27, 2026 Participant: Nate Nielsen #41196 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Strong Second Mile Anchors a Steady 5K Nate Nielsen finished the 2026 Boulderthon 5K in 28:12, covering the 3.1 miles at a 9:05 per-mile pace. His race opened with an 8:56 first mile, sharpened into an 8:29 second mile his fastest of the day before easing to 9:57 over the closing mile to the finish. That middle mile stood out as the highlight of his run, showing a strong surge in the race's second third before the pace settled back down. Racing at Boulder's altitude of over 5,000 feet adds context to that opening pace and the overall time, given the thinner air throughout the course. With his 5K experience logged, Nielsen has a clear data point to build from if he returns to Boulderthon.
