Date: Sept. 27, 2026 Participant: Colleen Liebers #13357 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Marathon Effort Fades Gracefully Down the Stretch Colleen Liebers finished the 2026 Boulderthon Marathon in 4:31:07, an overall pace of 10:20 per mile across the 26.2-mile course. She opened quickly, covering her first two miles in roughly 8:56 pace apiece, then settled into a rhythm through the middle miles, holding between 9:15 and 9:40 per mile from mile 6 through mile 17. The closing miles cooled to the 12-minute range as fatigue set in, but the overall arc showed a controlled front half giving way gradually rather than collapsing late. That early two-mile stretch stands as the strongest sustained running of her day, nearly a minute and a half per mile faster than her overall average pace. Fittingly, she closed things out on the historic Pearl Street Mall in downtown Boulder, a city sitting above 5,000 feet of elevation a fitting backdrop for a well-paced, patient marathon effort.
