Interpretation
Adam (SCR-DR) started at 8:52 AM; Duncan (P-DR) started at 8:42 AM. That gave Duncan a 10 minutes head start on Adam. On foot, Adam ran 1:11:20 and Duncan ran 1:21:09 — Adam was 9:49 faster than Duncan. Adam took official place 689th (time-based 360th) and Duncan took official place 686th (time-based 682nd). Duncan's head start was enough to flip the official order even though Adam was faster on foot. Biggest swing: Adam gained 5:16 from Muir Woods to Cardiac.
