Interpretation
John (Z-DR) started at 8:51 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 27 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:13:27 and Edward ran 48:29 — Edward was 24:58 faster than John. John took official place 710th (time-based 435th) 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 9:13 from Muir Woods to Cardiac.
