Strong Start, Need for Sustained Endurance Riley Jennings maintained a consistent pace in the early stages of the race, logging several 7:34 min/mile splits from mile 1 through mile 3 and holding pace within 7:347:39 min/mile until mile 7. By mile 10, the elapsed time was 1:18:33, and pacing remained strong at 7:51 min/mile, with a gradual change detectable as the race progressed. Despite the promising start, a slower pace was evident from mile 16 onward, where the average pace began to increase steadily, peaking with a 9:42 min/mile split at mile 16 and eventually reaching 11:25 min/mile by mile 26. The split time of 18:16 at mile 19 suggests this was a particularly challenging portion. Working on maintaining energy for the later stages could improve overall consistency. With an overall finishing time of 4:12:46, theres potential for pacing strategies to enhance late-race performance.
