Tien (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Tien because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tien ran 2:02:54 and Edward ran 48:29 — Edward was 1:14:25 faster than Tien. Tien took official place 1348th (time-based 1303rd) 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 28:53 from Muir Woods to Cardiac.
