Date: Sept. 28, 2025 Participant: Alexander Sheppard #12427 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

8:00 Peak Mile, 1:53 First Half, 4:24:04 Finish Time: 4:24:04 (10:04/mi). First half 1:53:17; second half 2:30:47 (+37:30). Early rhythm: miles 1–2 at 9:01, miles 4–6 at 8:36, mile 10 at 8:19, fastest mile 12 at 8:00. Through mile 16, most splits stayed 8:36–9:11. From mile 20 onward: 10:17, 10:57, 11:44, 12:23, 16:46, 16:45, 14:23. Coaching notes: The strong miles 4–12 suggest capacity for an even 8:45–8:55 pace. For next build, emphasize: progressive long runs finishing last 6–8 miles at goal pace; marathon-pace blocks after 90–120 minutes (e.g., 3×2 mi at 8:45–8:55 with short jogs); first 5 miles around 8:55–9:00 to preserve late strength; weekly strides and light strength (single-leg work, calf/hip stability) to support late-mile form.
