Robb (Q-DR) started at 8:43 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 19 minutes head start on Robb because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robb ran 1:57:08 and Edward ran 48:29 — Edward was 1:08:39 faster than Robb. Robb took official place 1290th (time-based 1274th) 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 28:17 from Muir Woods to Cardiac.
