Interpretation
Tracy (G-DR) started at 8:35 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 11 minutes head start on Tracy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Tracy ran 1:40:10 and Edward ran 48:29 — Edward was 51:41 faster than Tracy. Tracy took official place 958th (time-based 1095th) 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 17:53 from Muir Woods to Cardiac.
