Strong Early Splits, Late-Mile Fade Highlights Pacing to Refine 3:10:33 finish (26.2 mi at 7:16/mile). Miles 1–5 ranged 6:12–6:27; mile 10–12 rebounded to 6:13–6:08, with 13 miles in 1:23:15. Pace softened from mile 16: 7:50 and 7:15 at 16–17, peaking at 10:02 at mile 22; closing miles sat mostly 8:30–9:10. To convert the sharp first half into an even overall, aim for late-endurance emphasis: progressive long runs (last 6–8 at goal pace), marathon-pace blocks after 90 min (e.g., 2×4–5 mi @ MP with short jog), and controlled early pacing to keep miles 10–15 closer to 6:20–6:30. Add strides and light strength to support economy.
