Interpretation
John (B-DR) started at 8:30 AM; Eric (W-DR) started at 8:48 AM. That gave John a 18 minutes head start on Eric. On foot, John ran 1:23:14 and Eric ran 1:05:45 — Eric was 17:29 faster than John. John took official place 570th (time-based 747th) and Eric took official place 573rd (time-based 204th). John's head start was enough to flip the official order even though Eric was faster on foot.
