Interpretation
Zach (K-DR) started at 8:38 AM; Ben (Y-DR) started at 8:50 AM. That gave Zach a 12 minutes head start on Ben. On foot, Zach ran 1:14:54 and Ben ran 1:03:20 — Ben was 11:34 faster than Zach. Zach took official place 567th (time-based 477th) and Ben took official place 571st (time-based 143rd). Zach's head start was enough to flip the official order even though Ben was faster on foot.
