Robert (R-DR) started at 8:44 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 20 minutes head start on Robert because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robert ran 1:27:43 and Edward ran 48:29 — Edward was 39:14 faster than Robert. Robert took official place 879th (time-based 857th) 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 16:19 from Muir Woods to Cardiac.
