Date: Sept. 27, 2026 Participant: Ian De Mallie #10399 Race: 2026 Boulderthon Marathon Distance: 26.2 miles

Steady Early Pace Gives Way to a Tough Back Stretch Ian De Mallie finished the marathon in 4:25:51, built on a strong and disciplined first half. Through 13.1 miles he clocked 1:53:13, averaging 8:42 per mile, with splits tightening as low as 8:12 in mile 11. That control held through mile 19, but the final 10K brought a steady fade, with mile splits stretching into the mid-teens by miles 24 and 26 as the effort wore on. Passing mile 22.5, near the lululemon Power-Up Zone, De Mallie's elapsed time stood at 3:22:09, still moving at a 9:11 average pace before the late slowdown set in. Racing at altitude, on a 2026 course reworked to trim net elevation gain to 603 feet, the opening 20 miles showed real strength a foundation worth building from for future pacing over the closing miles.
