Interpretation

Ben (Y-DR) started at 8:50 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 40 minutes head start on Ben because the Runner wave starts 27 minutes after the Invitational wave. On foot, Ben ran 1:27:42 and Chris ran 1:00:42 — Chris was 27:00 faster than Ben. Ben took official place 1035th (time-based 855th) 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 12:04 from Muir Woods to Cardiac.
