Date: Sept. 28, 2025 Participant: Sean Murray #12462 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

Aggressive Start, +23:46 Positive Split, Late Rebound 3:36:26 for 26.2 (8:15/mi). First half 1:36:20; second half 2:00:06 (+23:46). Early 10-mile average 7:19/mi with a 7:02 best (mile 5). Pace drift began after mile 16 (10:05 at 17; 10:38 at 23). Final 10K 59:45 (9:38/mi), but you regained rhythm late: 8:53 at 25 and 8:36 at 26. 194/2678 overall (~top 7%). For next time, cap the first 10 miles near target marathon pace to reduce late drop-off; avoid sub-7:15 surges early. Build fatigue resistance with: long runs 18–22 mi finishing with 6–8 at marathon pace; steady-state/tempo 30–45 min; long progressions from easy to MP; short hill sprints/strides for economy. Practice even-effort pacing through 20 miles, then progress if available.
