9:03/mi for 16 Miles, 4:31:09 Finish Official time 4:31:09 (10:20/mi). Miles 1–6 held 8:49–9:06. 10 miles in 1:29:50; 13 miles in 1:56:51 (8:59/mi). Fastest splits: mile 12 in 8:22 and mile 10 in 8:46. Pace shifted at mile 17 (10:05); miles 18–24 included 11:08, 11:46, 12:41, 13:31, and 17:00. Closed with 10:58 (mile 25) and 11:56 (mile 26). Coaching notes: Early pacing was consistent; the key is minimizing late fade. Target weekly long runs with progression finishes (5–8 mi easy, then 6–8 mi at 9:50–10:10/mi). Add marathon-effort workouts like 3×2 mi at 9:50–10:10 with short jogs, plus strength and hill strides to bolster fatigue resistance. Prior half at 9:15/mi indicates solid speed; extending that rhythm beyond mile 16 should bring the overall pace down.
