Nathan (N-DR) started at 8:41 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 17 minutes head start on Nathan because the Runner wave starts 27 minutes after the Invitational wave. On foot, Nathan ran 1:28:05 and Edward ran 48:29 — Edward was 39:36 faster than Nathan. Nathan took official place 809th (time-based 867th) 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 14:51 from Muir Woods to Cardiac.
