Interpretation
Raymond (U-DR) started at 8:46 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 22 minutes head start on Raymond because the Runner wave starts 27 minutes after the Invitational wave. On foot, Raymond ran 1:16:25 and Edward ran 48:29 — Edward was 27:56 faster than Raymond. Raymond took official place 674th (time-based 537th) 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 11:57 from Muir Woods to Cardiac.
