Interpretation

John (Z-DR) started at 8:51 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 41 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:13:27 and Chris ran 1:00:42 — Chris was 12:45 faster than John. John took official place 710th (time-based 435th) 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 4:55 from Muir Woods to Cardiac.
