William (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on William because the Runner wave starts 27 minutes after the Invitational wave. On foot, William ran 1:51:59 and Edward ran 48:29 — Edward was 1:03:30 faster than William. William took official place 1258th (time-based 1246th) 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 25:37 from Muir Woods to Cardiac.
