Date: Sept. 27, 2026 Participant: Breck Dunbar #10298 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Anchors a Strong Marathon Finish Breck Dunbar completed the marathon in 4:05:55, holding an 8:048:46 min/mile rhythm through the first ten miles before a gradual fade in the second half brought her overall pace to 9:23 min/mile. The early consistency built a solid foundation, with the closing miles understandably settling into an easier effort as fatigue set in over the back half of the course. Her strongest stretch came in miles 1 through 10, where she averaged roughly 8:16 min/mile, the fastest sustained running of her race. That effort came at Boulder's elevation of over 5,000 feet, adding weight to the pace she carried through those early miles. She crossed the finish on the Pearl Street Mall in downtown Boulder, capping the effort in the city National Geographic once named the Happiest City in America.
