Eric (W-DR) started at 8:48 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 24 minutes head start on Eric because the Runner wave starts 27 minutes after the Invitational wave. On foot, Eric ran 1:05:45 and Edward ran 48:29 — Edward was 17:16 faster than Eric. Eric took official place 573rd (time-based 204th) 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 6:57 from Muir Woods to Cardiac.
