Date: Sept. 27, 2026 Participant: Andrew Greenstein #31567 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Miles Give Way to a Late Fade at the Finish Andrew Greenstein completed the 2026 Boulderthon 10K in 1:04:33, an average pace of 10:24 per mile. His race built steadily through the middle miles, holding pace between 9:50 and 10:37 from mile two through mile five before the final mile slowed to 12:11, pulling his overall average back. His strongest stretch came early, covering the first mile in 9:35, the fastest mile of his race. Racing through Boulder, sitting above 5,000 feet of elevation, adds context to the effort required to hold that opening pace. Should Andrew return to Boulderthon, working to sustain that early rhythm through the closing mile could offer a smoother overall finish.
