Interpretation
Patrick (P-DR) started at 8:42 AM; Mark (R-DR) started at 8:44 AM. That gave Patrick a 2 minutes head start on Mark. On foot, Patrick ran 1:44:35 and Mark ran 1:43:10 — Mark was 1:25 faster than Patrick. Patrick took official place 1188th (time-based 1159th) and Mark took official place 1192nd (time-based 1140th). Patrick's head start was enough to flip the official order even though Mark was faster on foot. Biggest swing: Patrick gained 2:07 from Muir Woods to Cardiac.
