Tracy (L-DR) started at 8:39 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 15 minutes head start on Tracy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tracy ran 2:05:03 and Edward ran 48:29 — Edward was 1:16:34 faster than Tracy. Tracy took official place 1315th (time-based 1310th) 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 28:14 from Muir Woods to Cardiac.
