Eric (L-INV) started at 8:12 AM; Mark (Q-INV) started at 8:16 AM. That gave Eric a 4 minutes head start on Mark. On foot, Eric ran 1:10:46 and Mark ran 1:07:00 — Mark was 3:46 faster than Eric. Eric took official place 101st (time-based 351st) and Mark took official place 104th (time-based 232nd). Eric's head start was enough to flip the official order even though Mark was faster on foot.
