Interpretation
Doug (W-DR) started at 8:48 AM; John (Z-DR) started at 8:51 AM. That gave Doug a 3 minutes head start on John. On foot, Doug ran 1:16:26 and John ran 1:13:27 — John was 2:59 faster than Doug. Doug took official place 708th (time-based 538th) and John took official place 710th (time-based 435th). Doug's head start was enough to flip the official order even though John was faster on foot. Biggest swing: John gained 3:34 from Muir Woods to Cardiac.
