Date: Sept. 28, 2025 Participant: Rie Hayes #10360 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, midrace stall, decisive late surge 26.2 in 6:28:04 (14:48/mi). Fastest mile 1 at 8:46. 10-mile split 1:59:17. Midrace splits: 10–13 in 20:45, 27:15, 26:36, 29:51. Rebound late: miles 23–26 at 6:23/mi; miles 21–26 averaged ~10:25/mi. Coaching notes: dial back the opener—keep miles 1–3 within ~+15–30 sec of intended marathon pace to stabilize later miles. Target steadier midrace output by practicing long runs with 3–6 miles at consistent effort and capped variability (±30–45 sec/mi). Retain the late push, but aim to bring the middle miles closer to even pacing.
