Date: Sept. 27, 2026 Participant: Jonathan Sarmini #32630 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Strong Middle Miles Power a Sub-Hour 10K Jonathan Sarmini finished the 2026 Boulderthon 10K in 59:59, holding a 9:40 min/mile pace across the 6.2-mile course. His race built steadily through the middle miles: after an opening 9:43 first mile, he clicked off consecutive miles of 9:00 and 8:58, his fastest mile-plus stretch of the day, before easing through miles four and five near 9:15-9:25 pace. The final mile slowed to 11:33, closing out the effort. The 10K field started at 8:10 AM in downtown Boulder, a city sitting above 5,000 feet of elevation, before finishing on the historic Pearl Street Mall. Given the strong pace through miles two and three, Sarmini might look at ways to sustain that rhythm deeper into the race next time out.
