Date: Sept. 28, 2025 Participant: Holger Mueller #11559 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

Brisk start, marked positive split, steady late rally Finish 4:30:12 (10:18/mi). First 10 miles ranged 8:35–9:01; fastest miles were 12 (8:33), 10 (8:35), 5 (8:36). Half split 1:55:34; second half 2:34:38 for a +39:04 positive split. Slowest stretch miles 22–24 (13:05–13:19), with a brief rebound at mile 19 (9:47) and a steadier close at 25–26 (12:38, 12:23). Previous result: 2024 half 1:53:46 (8:41/mi); marathon halfway was +1:48. For a smoother marathon, align early pace with goal (keep miles 1–10 near 10:10–10:25/mi), then aim to hold 10:20–10:40 through miles 16–22. Build this with long runs featuring 2×5–6 miles at marathon pace after mile 12 and finish-fast 3–6 miles. Add periodic form checks and short 20–30s resets at miles 18–24 to curb deceleration.
