Tommy (Y-DR) started at 8:50 AM; Mark (Z-DR) started at 8:51 AM. That gave Tommy a 1 minute head start on Mark. On foot, Tommy ran 1:10:24 and Mark ran 1:09:26 — Mark was 0:58 faster than Tommy. Tommy took official place 644th (time-based 338th) and Mark took official place 645th (time-based 308th). Tommy's head start was enough to flip the official order even though Mark was faster on foot.
