Interpretation

Tom (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Tom because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tom ran 1:18:02 and Edward ran 48:29 — Edward was 29:33 faster than Tom. Tom took official place 788th (time-based 583rd) 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 12:23 from Muir Woods to Cardiac.
