Date: Sept. 27, 2026 Participant: Annie Laurenz #10254 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Fuels Strong Marathon Effort at Altitude Annie Laurenz completed the 2026 Boulderthon Marathon in 3:58:00, averaging 9:05 per mile. Her race unfolded in two distinct halves: a controlled, even first 13 miles hovering near 8:35 pace, followed by a natural easing through the second half as fatigue and distance accumulated, with mile splits gradually extending into the 10:30s by miles 21-25. The first 10 miles stood out as her most consistent stretch, holding between 8:20 and 8:58 per mile a strong display of pacing discipline through Boulder's roads, which sit above 5,000 feet of elevation. As she approached the marathon's lululemon Power-Up Zone near mile 22.5, her pace had settled into the 10:40 range, reflecting the cumulative demand of the back half. Maintaining more of that early rhythm into the closing miles could be a useful focus for future long-distance efforts.
