Interpretation
Susan (J-DR) started at 8:37 AM; Mark (R-DR) started at 8:44 AM. That gave Susan a 7 minutes head start on Mark. On foot, Susan ran 1:49:55 and Mark ran 1:43:10 — Mark was 6:45 faster than Susan. Susan took official place 1190th (time-based 1226th) and Mark took official place 1192nd (time-based 1140th). Susan's head start was enough to flip the official order even though Mark was faster on foot. Biggest swing: Mark gained 3:00 from Muir Woods to Cardiac.
