Date: Sept. 27, 2026 Participant: Tanner Mottau #32993 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Start Gives Way to a Hard-Earned Finish Tanner Mottau completed the 2026 Boulderthon 10K in 1:02:56, part of a field of 3,071. Mottau opened briskly, covering his first mile in 9:06 and his second in 8:47, the fastest mile of his race. From there, each successive mile slowed incrementally, with his pace settling into the 9:20-9:50 range through mile four and easing further into the 10:00-13:00 range over the final two miles. The cumulative pace reflects a runner who banked time early and managed the back half more conservatively. Given Boulder's elevation above 5,000 feet, that early pace stands out as the strongest stretch of the day. Consider working toward a more even split next time out, holding a touch more in reserve over the opening miles to sustain that early rhythm longer into the race.
