Interpretation
Ben (Y-DR) started at 8:50 AM; Madeleine (Q-DR) started at 8:43 AM. That gave Madeleine a 7 minutes head start on Ben. On foot, Ben ran 1:17:09 and Madeleine ran 1:24:06 — Ben was 6:57 faster than Madeleine. Ben took official place 775th (time-based 559th) and Madeleine took official place 773rd (time-based 773rd). Madeleine's head start was enough to flip the official order even though Ben was faster on foot. Biggest swing: Ben gained 2:01 from Muir Woods to Cardiac.
