Date: Sept. 27, 2026 Participant: Libby Peter #31539 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Steady Start Fuels a Determined Finish Libby Peter completed the 2026 Boulderthon 10K in 1:13:46, part of a field of 3,071 in a race that finishes on the Pearl Street Mall in downtown Boulder. Peter's opening mile was her quickest, clocked at 10:18, and her cumulative pace eased gradually from there, settling at 11:52 min/mile by the finish. Her strongest stretch came through the first two miles, where she covered ground at just over a 10:30 min/mile pace before the back half of the race saw a natural tapering. Given Boulder's elevation above 5,000 feet, that early pace stands out as a solid foundation. A slightly more even pacing plan over the middle miles could help her carry that early speed further into future races.
