Athlete B

Interpretation

Dan (Y-DR) started at 8:50 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 40 minutes head start on Dan because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dan ran 1:11:34 and Chris ran 1:00:42 — Chris was 10:52 faster than Dan. Dan took official place 662nd (time-based 373rd) 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 6:56 from Muir Woods to Cardiac.
