Steady Pace Carries Him Through a Consistent 10K Jack Cline finished the 2026 Boulderthon 10K in 1:00:34, averaging 9:46 per mile. His mile splits stayed remarkably tight through the first four miles, holding between 9:35 and 9:46, before a strong fifth mile at 9:14 his fastest of the race. The final mile slowed to 10:37, a common pattern as runners settle in before the finish. Cline's race unfolded on the 2026 Boulderthon course, which finishes on the Pearl Street Mall in downtown Boulder, a city sitting above 5,000 feet of elevation. His even-effort pacing through the middle miles reflects solid course management at altitude, and there's room to experiment with a slightly more conservative early pace to preserve strength for a stronger closing mile next time out.
