Interpretation
Rachael (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on Rachael because the Runner wave starts 27 minutes after the Invitational wave. On foot, Rachael ran 2:03:53 and Edward ran 48:29 — Edward was 1:15:24 faster than Rachael. Rachael took official place 1321st (time-based 1305th) 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 24:31 from Muir Woods to Cardiac.
