Italo (Z-DR) started at 8:51 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 27 minutes head start on Italo because the Runner wave starts 27 minutes after the Invitational wave. On foot, Italo ran 1:19:29 and Edward ran 48:29 — Edward was 31:00 faster than Italo. Italo took official place 844th (time-based 632nd) 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 12:43 from Muir Woods to Cardiac.
