Adam (SCR-DR) started at 8:52 AM; Julia (Q-INV) started at 8:16 AM. That gave Julia a 36 minutes head start on Adam because the Runner wave starts 27 minutes after the Invitational wave. On foot, Adam ran 1:11:20 and Julia ran 57:02 — Julia was 14:18 faster than Adam. Adam took official place 689th (time-based 360th) 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 6:38 from Muir Woods to Cardiac.
