Interpretation
Thomas (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Thomas because the Runner wave starts 27 minutes after the Invitational wave. On foot, Thomas ran 1:19:14 and Edward ran 48:29 — Edward was 30:45 faster than Thomas. Thomas took official place 812th (time-based 624th) 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 10:56 from Muir Woods to Cardiac.
