JC (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on JC because the Runner wave starts 27 minutes after the Invitational wave.

Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 13:18 from Muir Woods to Cardiac.
