Interpretation
Tom (F-DR) started at 8:34 AM; BJ (Y-DR) started at 8:50 AM. That gave Tom a 16 minutes head start on BJ. On foot, Tom ran 1:41:38 and BJ ran 1:25:46 — BJ was 15:52 faster than Tom. Tom took official place 971st (time-based 1118th) and BJ took official place 976th (time-based 806th). Tom's head start was enough to flip the official order even though BJ was faster on foot.
