Robb (Q-DR) started at 8:43 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 33 minutes head start on Robb because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robb ran 1:57:08 and Chris ran 1:00:42 — Chris was 56:26 faster than Robb. Robb took official place 1290th (time-based 1274th) 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 23:59 from Muir Woods to Cardiac.
