Steady Start, Mid-Race Pop, Late-Race Learnings Marathon finish: 4:29:07 for 26.2 miles (10:16/mi). Held a consistent rhythm through mile 17 with elapsed pace hovering 9:13–9:24/mi. Fastest miles: 12 in 8:34 and 10 in 8:57; mile 8 also strong at 9:03. Early miles 1–6 were tightly grouped (9:14–9:31). Pace decelerated after mile 18 (11:24), with notable late splits at mile 21 (12:31) and mile 24 (14:49). To convert the strong opening into a faster overall, practice marathon-pace long runs finishing the last 6–8 miles near 9:15–9:25/mi, add progressive long runs that gently cut down from 9:30 to 9:00/mi by mile 12, and include steady tempo segments (20–30 minutes) around 8:45–9:00/mi. Rehearse pacing to keep miles 18–23 within +15–30 sec of goal pace, and use brief form checks each mile to stabilize cadence when fatigue rises.
