Consistent Splits with Strong Improvement Mid-Race Ryan showed a remarkable improvement from the start, beginning with a 7:36 min/mile pace at mile 1 and aggressively decreasing to 7:06 min/mile by mile 3. Notably, his best split pace of 6:52 min/mile came between miles 1 and 2, indicating a strong acceleration early in the race. By mile 5, he achieved his highest position of 25th in his division, hinting at strategic pacing and energy management. Throughout the race, Ryan maintained relatively consistent lap splits, with some variance in the latter half. In particular, his pacing began to slow from mile 6, with his pace increasing to 8:25 min/mile by mile 8. Gradual adjustment in pace could be refined to sustain earlier momentum. Finishing the half marathon in 1:40:29, Ryan achieved an overall elapsed pace of 7:40 min/mile, concluding in a strong position for future improvement targets. Continued focus could refine endurance in the latter stage.
