Colin (Y-DR) started at 8:50 AM; Julia (Q-INV) started at 8:16 AM. That gave Julia a 34 minutes head start on Colin because the Runner wave starts 27 minutes after the Invitational wave. On foot, Colin ran 1:10:27 and Julia ran 57:02 — Julia was 13:25 faster than Colin. Colin took official place 646th (time-based 340th) 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 6:43 from Muir Woods to Cardiac.
