BJ (Y-DR) started at 8:50 AM; Kenji (P-DR) started at 8:42 AM. That gave Kenji a 8 minutes head start on BJ. On foot, BJ ran 1:25:46 and Kenji ran 1:33:41 — BJ was 7:55 faster than Kenji. BJ took official place 976th (time-based 806th) and Kenji took official place 974th (time-based 979th). Kenji's head start was enough to flip the official order even though BJ was faster on foot.
