Fast Opening, Late Slowdown, Clear Pacing Takeaways Marathon finish 3:50:51 (8:48/mile). Through 6 miles: 45:06 (7:31). 10-mile elapsed pace 7:39; 13 miles in 1:41:00 (7:46). Fastest mile: 7:18 (mile 2); strong rebound at mile 5 in 7:23 after 7:40 at mile 4. From miles 17–18: 9:19/9:37; slowest mile 24 in 11:54; closed mile 26 in 10:10. Prior half: 1:43:18 (7:53). Coaching notes: Aim to cap the first 10K near goal marathon pace to limit late fade; early 7:18–7:40 segments exceeded the 8:48 average. Build fatigue resistance with long runs finishing 6–8 miles at marathon pace and midweek medium-long runs. Add 20–30 minute tempos near half-marathon effort, plus strides and light strength work to preserve form in miles 20–26. Practice even-split rehearsals in tune-up races to refine pacing.
