Interpretation
Walter (AAA-DR) started at 8:27 AM; Lou (AAA-INV) started at 8:00 AM. That gave Lou a 27 minutes head start on Walter because the Runner wave starts 27 minutes after the Invitational wave. On foot, Walter ran 2:49:57 and Lou ran 3:12:10 — Walter was 22:13 faster than Lou. Walter took official place 1388th (time-based 1385th) and Lou took official place 1385th (time-based 1397th). Lou's head start was enough to flip the official order even though Walter was faster on foot. Biggest swing: Walter gained 5:28 from Muir Woods to Cardiac.
