Interpretation

Colin (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Colin because the Runner wave starts 27 minutes after the Invitational wave. On foot, Colin ran 1:10:27 and Edward ran 48:29 — Edward was 21:58 faster than Colin. Colin took official place 646th (time-based 340th) 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 9:17 from Muir Woods to Cardiac.
