Samantha (N-DR) started at 8:41 AM; Julia (Q-INV) started at 8:16 AM. That gave Julia a 25 minutes head start on Samantha because the Runner wave starts 27 minutes after the Invitational wave. On foot, Samantha ran 1:29:33 and Julia ran 57:02 — Julia was 32:31 faster than Samantha. Samantha took official place 848th (time-based 896th) 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 14:42 from Muir Woods to Cardiac.
