Date: Sept. 27, 2026 Participant: Geoffrey Zarzecki #41101 Race: 2026 Boulderthon 5K Distance: 3.1 miles

A Strong Middle Mile Powers a Steady 5K Finish Geoffrey Zarzecki completed the 2026 Boulderthon 5K in 29:30, an overall pace of 9:31 per mile. His race shape showed a clear surge at the midpoint: after opening in 10:09 for the first mile, he dropped to 8:17 for the second his fastest mile of the day before settling back to 10:00 to close things out. That middle-mile push moved him up significantly in the standings before the finish. Racing at Boulder's altitude of over 5,000 feet, a locale also known as the Happiest City in America, Zarzecki's ability to accelerate mid-race stands out as the highlight of his effort. Holding more of that second-mile rhythm through the final stretch could be a rewarding focus next time out.
