Date: Sept. 28, 2025 Participant: Owen Aston #11803 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

Even Start, Midrace Surge, Late Slowdown Finish 4:24:50 (10:06/mi). Miles 1–6 averaged 9:17/mi (range 8:59–9:50). A midrace dip at mile 7 (10:47) was followed by the day’s fastest splits at miles 10 and 12 (8:47). 10-mile split 1:33:28; 20-mile split 3:11:04. Pace decelerated after mile 20, with a peak slowdown at mile 24 (13:08), and a close of 11:22 for mile 26. Coaching notes: Aim for steadier pacing through miles 7–12 to reduce spikes, then protect the back half. Try long runs of 16–20 miles with the last 4–6 miles at marathon pace to rehearse miles 20–26. Practice conservative midrace caps (no faster than ~8:55–9:05 when average is ~9:17) to save energy. Include late-effort tempos and moderate hill work to support stronger splits after mile 20.
