Date: Sept. 27, 2026 Participant: Esme Eberstadt #11283 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Pace Build Delivers a Strong Marathon Finish Esme Eberstadt crossed the line in 4:31:08, closing the 26.2-mile course with the race's cumulative pace tightening from 10:57 per mile at the first marker to 10:22 by the finish. Her best full mile came at mile 15, covered in 9:45, part of a stretch from mile 11 through 21 where she consistently ran under her overall average. The final six miles held firm in the 9:5910:46 range, a sign of well-managed effort deep into the race. Boulder sits above 5,000 feet, a backdrop for any marathon pace here. The 2026 course also carried a redesigned, lighter elevation profile than in past years, and Eberstadt's late push through the miles near the lululemon Power-Up Zone, around mile 22.5, held steady before she finished on the Pearl Street Mall in downtown Boulder.
