Interpretation

David (G-DR) started at 8:35 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 25 minutes head start on David because the Runner wave starts 27 minutes after the Invitational wave. On foot, David ran 1:58:23 and Chris ran 1:00:42 — Chris was 57:41 faster than David. David took official place 1252nd (time-based 1281st) 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 23:07 from Muir Woods to Cardiac.
