Karen (H-DR) started at 8:36 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 12 minutes head start on Karen because the Runner wave starts 27 minutes after the Invitational wave. On foot, Karen ran 2:00:59 and Edward ran 48:29 — Edward was 1:12:30 faster than Karen. Karen took official place 1277th (time-based 1293rd) 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 27:17 from Muir Woods to Cardiac.
