Interpretation
Jason (V-DR) started at 8:47 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 23 minutes head start on Jason because the Runner wave starts 27 minutes after the Invitational wave. On foot, Jason ran 1:21:08 and Edward ran 48:29 — Edward was 32:39 faster than Jason. Jason took official place 790th (time-based 681st) 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 13:49 from Muir Woods to Cardiac.
