Date: Sept. 28, 2025 Participant: Billy Kozma #13054 Race: 2025 Boulderthon Marathon Distance: 26.2 miles Weather: Perfect running weather with temperatures in the 50's to 70's and nice cloud cover

Fast start, significant positive split with late slowdown First 26.2 in 3:43:24 (8:31/mi). First 10 miles averaged 7:12/mi; fastest split was mile 12 in 6:55. Halfway at 1:33:45; second half 2:09:39. From mile 17 onward, average pace was 10:29/mi, with a notable drop at mile 20 (11:32) and the slowest mile at 24 (11:57). Coaching notes: Early rhythm of 7:03–7:19 shows strong aerobic speed. Focus on even pacing and late-race durability: long runs finishing with 6–10 miles at goal marathon effort, and marathon-pace segments after 90 minutes. Rehearse restraint before mile 13 to avoid mid-race surges. Stabilize the back half by targeting consistent effort through miles 17–22, where splits ranged 8:26–11:43, then progress if available.
