Date: Sept. 28, 2025 Participant: Emily Cogsdill #11113 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

Steady Midrace, Controlled Finish at 10:23 Pace 26.2 in 4:32:18 (10:23/mile). Miles 1–2: 9:57, 9:35. Split variability at miles 3–6, then miles 7–19 stayed mostly 9:30–10:36, highlighted by 9:15 at mile 12 and 9:30 at mile 10. Late miles 20–24 shifted to 11:05–11:48; closed miles 25–26 at 11:25–11:27. Half split ~2:10:15; second half 2:22:03 (positive split ~11:48). Compared to a 1:59:30 half (9:07/mile), marathon pace was +1:16/mile. To tighten pacing and sustain speed beyond mile 20, consider: long runs of 18–22 miles with the last 6–8 at 10:15–10:25, steady 8–10 mile tempos near 10:10–10:20, and cadence-focused easy runs to smooth early variability. Practicing pacing checkpoints at miles 3–6 and 18–24 can help keep late splits closer to the 10:20–10:40 range.
