Sean (W-DR) started at 8:48 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 24 minutes head start on Sean because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sean ran 1:37:47 and Edward ran 48:29 — Edward was 49:18 faster than Sean. Sean took official place 1171st (time-based 1064th) 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 21:48 from Muir Woods to Cardiac.
