Alexandra (AAA-DR) started at 8:27 AM; Chris (J-INV) started at 8:10 AM. That gave Chris a 17 minutes head start on Alexandra because the Runner wave starts 27 minutes after the Invitational wave. On foot, Alexandra ran 2:14:46 and Chris ran 1:00:42 — Chris was 1:14:04 faster than Alexandra. Alexandra took official place 1307th (time-based 1342nd) 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 26:37 from Muir Woods to Cardiac.
