Interpretation
Ed (L-DR) started at 8:39 AM; Ben (Y-DR) started at 8:50 AM. That gave Ed a 11 minutes head start on Ben. On foot, Ed ran 1:28:08 and Ben ran 1:17:09 — Ben was 10:59 faster than Ed. Ed took official place 774th (time-based 869th) and Ben took official place 775th (time-based 559th). Ed's head start was enough to flip the official order even though Ben was faster on foot. Biggest swing: Ben gained 3:03 from Muir Woods to Cardiac.
