Regina (B-DR) started at 8:30 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 6 minutes head start on Regina because the Runner wave starts 27 minutes after the Invitational wave. On foot, Regina ran 2:17:41 and Edward ran 48:29 — Edward was 1:29:12 faster than Regina. Regina took official place 1330th (time-based 1348th) 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 30:21 from Muir Woods to Cardiac.
