Sally (Q-DR) started at 8:43 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 33 minutes head start on Sally because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sally ran 1:57:58 and Chris ran 1:00:42 — Chris was 57:16 faster than Sally. Sally took official place 1296th (time-based 1278th) 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 22:11 from Muir Woods to Cardiac.
