Mark (Z-DR) started at 8:51 AM; Duncan (X-DR) started at 8:49 AM. That gave Duncan a 2 minutes head start on Mark. On foot, Mark ran 1:07:23 and Duncan ran 1:09:06 — Mark was 1:43 faster than Duncan. Mark took official place 615th (time-based 245th) and Duncan took official place 611th (time-based 293rd).
