Consistent Mid-Race Splits With Late Slowdown, Solid Finish Marathon finish 4:33:59 (10:27/mi). Early rhythm: 9:06, 9:06, 8:54. Variability mid-early: 12:43 at mile 4 followed by a 5:29 surge at mile 5. From miles 622 you held mostly 8:3610:10/mi, including sub-9s at 8, 10, 12, 16, and 19. Late miles dipped: 12:09 (23), 31:39 (24), 14:52 (25), then a steadier 10:22 to close mile 26. Coaching notes: aim for steadier effortavoid abrupt surges like mile 5 by locking into goal pace early and using lap-pace alerts. Build late-race durability with long runs that finish fast (last 46 miles at goal pace) and marathon-pace tempo blocks midweek. Add fatigue-resistance work: back-to-back runs or long runs with short walk breaks at fixed intervals to maintain pace. Practice even effort and refine pacing to carry your miles 622 consistency through the finish.
