Interpretation
John (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:04:45 and Edward ran 48:29 — Edward was 16:16 faster than John. John took official place 576th (time-based 175th) 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 7:58 from Muir Woods to Cardiac.
