Date: Sept. 27, 2026 Participant: Bobby Sorensen #11819 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Pacing Through Halfway, Grinding Home Strong Bobby Sorensen finished the 2026 Boulderthon Marathon in 3:57:53, holding a tight 8:108:20 min/mile pace through the first two-thirds of the race before the closing miles slowed into the 9:3012:20 min/mile range as fatigue set in over the final 10K. His strongest mile-long stretch came early, covering miles 9 through 10 in 7:52, part of a broader opening 13 miles that stayed remarkably consistent near 8:10 min/mile pace. That composure through the first half set up the overall finish, even as the closing miles cost time. Racing through Boulder, which sits above 5,000 feet of elevation, Sorensen's ability to hold form deep into the marathon before the late fade stands out as the defining feature of his day.
