Interpretation
MARK (M-DR) started at 8:40 AM; John (Z-DR) started at 8:51 AM. That gave MARK a 11 minutes head start on John. On foot, MARK ran 1:24:26 and John ran 1:13:27 — John was 10:59 faster than MARK. MARK took official place 709th (time-based 778th) and John took official place 710th (time-based 435th). MARK's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 5:07 from Muir Woods to Cardiac.
