David (AAA-DR) started at 8:27 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 3 minutes head start on David because the Runner wave starts 27 minutes after the Invitational wave. On foot, David ran 2:13:32 and Edward ran 48:29 — Edward was 1:25:03 faster than David. David took official place 1293rd (time-based 1340th) 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 35:52 from Muir Woods to Cardiac.
