Interpretation
Kenji (P-DR) started at 8:42 AM; Tom (F-DR) started at 8:34 AM. That gave Tom a 8 minutes head start on Kenji. On foot, Kenji ran 1:33:41 and Tom ran 1:41:38 — Kenji was 7:57 faster than Tom. Kenji took official place 974th (time-based 979th) and Tom took official place 971st (time-based 1118th). Tom's head start was enough to flip the official order even though Kenji was faster on foot.
