Interpretation
Peter (N-DR) started at 8:41 AM; Don (AAA-INV) started at 8:00 AM. That gave Don a 41 minutes head start on Peter because the Runner wave starts 27 minutes after the Invitational wave. On foot, Peter ran 2:32:27 and Don ran 3:11:24 — Peter was 38:57 faster than Don. Peter took official place 1386th (time-based 1370th) and Don took official place 1382nd (time-based 1396th). Don's head start was enough to flip the official order even though Peter was faster on foot. Biggest swing: Peter gained 21:27 from Muir Woods to Cardiac.
