Interpretation
Albert (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Albert because the Runner wave starts 27 minutes after the Invitational wave. On foot, Albert ran 1:21:19 and Edward ran 48:29 — Edward was 32:50 faster than Albert. Albert took official place 872nd (time-based 686th) 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 14:06 from Muir Woods to Cardiac.
