His performance positions him at 801st out of 6546 participants overall, 559th among males, and 90th in the Male 35-39 division. Notably, Dayton's initial split of 8:20 min/mile demonstrated a strong start, with some fluctuations toward the middle of the race. Most splits maintained a consistent pace, such as miles 7 and 8 at 8:16 and 8:17 min/mile, respectively.

While the dip at mile 3 affected his overall standing slightly, maintaining focus on consistent pacing throughout could enhance future results.
