Interpretation
Amy (AAA-DR) started at 8:27 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 3 minutes head start on Amy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Amy ran 2:27:00 and Edward ran 48:29 — Edward was 1:38:31 faster than Amy. Amy took official place 1349th (time-based 1362nd) 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 36:17 from Muir Woods to Cardiac.
