Interpretation
William (Z-DR) started at 8:51 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 27 minutes head start on William because the Runner wave starts 27 minutes after the Invitational wave. On foot, William ran 1:11:27 and Edward ran 48:29 — Edward was 22:58 faster than William. William took official place 675th (time-based 370th) 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 9:19 from Muir Woods to Cardiac.
