Date: Sept. 28, 2025 Participant: Jaime Campos #11816 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

Mid-race momentum with a composed close at sub-10 pace Marathon finish: 4:21:54 for 26.2 miles (9:59/mile). Best rhythm from miles 8–13, holding 8:24–8:31 with a fastest split of 8:02 at mile 12. After mile 15, splits moved into the 10:01–11:40 range, peaking at 15:19 (mile 23) before tightening to 10:53 in mile 26. Coaching notes: Leverage that 8:20s rhythm earlier and aim to extend it past mile 15. Prioritize long runs with 6–10 miles at steady marathon effort, progression long runs finishing near 8:30–9:30, and weekly 20–40 minute tempos around 8:20–8:40. Add short strides after easy runs for economy, and practice even pacing via mile-by-mile checks.
