Date: Sept. 28, 2025 Participant: William Bernicke #13424 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

Sub-4 achieved with mid-race surge; pacing to refine Finish: 3:55:02 (8:58/mi). Approximately top 15% of 2,678. Miles 1–13 averaged 8:36/mi; miles 14–26.2 averaged 9:21/mi (+0:45/mi). Fastest mile: 12 in 8:00. Most consistent stretch: miles 8–12 at ~8:20/mi. Late miles: 24–26 at 10:50, 10:33, 10:28. Coaching notes: Aim for steadier early pacing (cap first 10K around 8:45–8:50). Build late-race durability with long runs finishing fast (last 6–8 mi at 8:45–9:00), marathon-pace tempos (2×4–5 mi), and hill reps to reinforce form after mile 20. Even 8:50/mi throughout projects ~3:51.
