Interpretation
Adam (SCR-DR) started at 8:52 AM; Ephets (P-DR) started at 8:42 AM. That gave Ephets a 10 minutes head start on Adam. On foot, Adam ran 1:11:20 and Ephets ran 1:21:08 — Adam was 9:48 faster than Ephets. Adam took official place 689th (time-based 360th) and Ephets took official place 684th (time-based 680th). Ephets's head start was enough to flip the official order even though Adam was faster on foot. Biggest swing: Adam gained 3:08 from Muir Woods to Cardiac.
