Margaret (M-DR) started at 8:40 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 16 minutes head start on Margaret because the Runner wave starts 27 minutes after the Invitational wave. On foot, Margaret ran 1:45:34 and Edward ran 48:29 — Edward was 57:05 faster than Margaret. Margaret took official place 1166th (time-based 1173rd) 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 23:10 from Muir Woods to Cardiac.
