Date: Sept. 27, 2026 Participant: Laura Zaunbrecher #30652 Race: 2026 Boulderthon 10K Distance: 6.2 miles

Boulder Runner Trims Time in Repeat 10K Performance Laura Zaunbrecher finished the 2026 Boulderthon 10K in 41:58, placing 36th overall and 10th among women in a field of 3,071. That mark improves on her 2025 Boulderthon 10K result of 42:47, shaving nearly a minute off last year's time. Zaunbrecher opened fast, covering her first mile in 6:18, then settled into a steady rhythm between 6:27 and 6:54 through mile five. That opening mile stood as her quickest stretch of the race, anchoring a strong middle portion before a 7:44 close brought her home. Boulder's altitude, over 5,000 feet, adds context to the effort behind these paces.
