Date: Sept. 28, 2025 Participant: Brandon Lui #11716 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

17:31 PR with Strong Early Splits Finished 26.2 in 4:16:17 (9:46/mi), a 17:31 marathon PR from 4:33:48 (pace drop from 10:27/mi). Logged nine sub-9:30 miles, with a best of 8:49 at mile 12. Key checkpoints: 10 miles in 1:34:49, 20 miles in 3:11:42; last 10K in 1:04:35 (10:25/mi). Marathon pace was only 0:19/mi slower than your 2024 half pace (9:27/mi). Coaching notes: Early-mid surges at miles 10-12 (9:06, 9:27, 8:49) were followed by a fade after mile 18, including 10:15-11:17 miles. Next target: tighten pacing to 9:35-9:45 through 20, then progress. Aim to keep miles 20-26 closer to sub-10:00 by resisting midrace spikes and settling into steady effort.
