Date: Sept. 27, 2026 Participant: Josh Zimmer #41516 Race: 2026 Boulderthon 5K Distance: 3.1 miles

Steady Effort Caps a Solid 5K Debut Through Downtown Boulder Josh Zimmer completed the 2026 Boulderthon 5K in 33:28. The race unfolded in three distinct phases: an opening mile at 10:49, a strong middle mile at 9:08, and a final mile that eased to 12:26 as he approached the finish. That second mile stood out as his fastest stretch of the day, a solid mile of pace management before the effort settled in the closing stage. Zimmer's race finished on the Pearl Street Mall, the traditional finish line for every Boulderthon distance, in a city sitting over 5,000 feet of elevation. Given the altitude, his ability to hit a sub-9:10 mile mid-race reflects well on his pacing strategy for a Stillwater, MN runner tackling Boulder's air.
