Interpretation
Thomas (Y-DR) started at 8:50 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 40 minutes head start on Thomas because the Runner wave starts 27 minutes after the Invitational wave. On foot, Thomas ran 1:19:14 and Chris ran 1:00:42 — Chris was 18:32 faster than Thomas. Thomas took official place 812th (time-based 624th) and Chris took official place 1st (time-based 71st). Chris was faster on foot and finished ahead on the official clock too. Biggest swing: Chris gained 6:38 from Muir Woods to Cardiac.
