Steady Early Miles Power a Strong Marathon Finish Zach Wassmer completed the 2026 Boulderthon Marathon in 4:32:53, a 10:24 min/mile average pace. Wassmer's first ten miles were his most consistent stretch, holding between 9:17 and 10:09 min/mile and settling into a 9:33 min/mile cumulative pace by mile 10. That effort held firm through the half-way point, with cumulative pace still near 9:33 min/mile at mile 13. The back half saw a gradual fade, with per-mile splits drifting past 10 minutes from mile 14 onward and into the 12-minute range by mile 22, near where the lululemon Power-Up Zone sits around mile 22.5. Even with that late slowdown, the front-half strength anchored his overall pace across the full 26.2 miles, run at over 5,000 feet of elevation in Boulder.
