Suzy (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on Suzy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Suzy ran 1:48:43 and Edward ran 48:29 — Edward was 1:00:14 faster than Suzy. Suzy took official place 1232nd (time-based 1219th) 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 24:05 from Muir Woods to Cardiac.
