Interpretation
Roger (N-DR) started at 8:41 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 17 minutes head start on Roger because the Runner wave starts 27 minutes after the Invitational wave. On foot, Roger ran 1:27:24 and Edward ran 48:29 — Edward was 38:55 faster than Roger. Roger took official place 798th (time-based 848th) and Edward took official place 2nd (time-based 1st). Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 12:01 from Muir Woods to Cardiac.
