Interpretation

Dan (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Dan because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dan ran 1:11:34 and Edward ran 48:29 — Edward was 23:05 faster than Dan. Dan took official place 662nd (time-based 373rd) 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 11:14 from Muir Woods to Cardiac.
