Interpretation

Sam (W-DR) started at 8:48 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 24 minutes head start on Sam because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sam ran 1:21:46 and Edward ran 48:29 — Edward was 33:17 faster than Sam. Sam took official place 827th (time-based 701st) 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 14:35 from Muir Woods to Cardiac.
