Jon (Y-DR) started at 8:50 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 40 minutes head start on Jon because the Runner wave starts 27 minutes after the Invitational wave. On foot, Jon ran 1:10:43 and Chris ran 1:00:42 — Chris was 10:01 faster than Jon. Jon took official place 649th (time-based 347th) 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 5:12 from Muir Woods to Cardiac.
