Sally (Q-DR) started at 8:43 AM; Julia (Q-INV) started at 8:16 AM. That gave Julia a 27 minutes head start on Sally because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sally ran 1:57:58 and Julia ran 57:02 — Julia was 1:00:56 faster than Sally. Sally took official place 1296th (time-based 1278th) and Julia took official place 3rd (time-based 32nd). Julia was faster on foot and finished ahead on the official clock too. Biggest swing: Julia gained 23:55 from Muir Woods to Cardiac.
