Christopher (W-DR) started at 8:48 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 24 minutes head start on Christopher because the Runner wave starts 27 minutes after the Invitational wave. On foot, Christopher ran 1:40:52 and Edward ran 48:29 — Edward was 52:23 faster than Christopher. Christopher took official place 1210th (time-based 1109th) 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 20:57 from Muir Woods to Cardiac.
