Robb (Q-DR) started at 8:43 AM; Julia (Q-INV) started at 8:16 AM. That gave Julia a 27 minutes head start on Robb because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robb ran 1:57:08 and Julia ran 57:02 — Julia was 1:00:06 faster than Robb. Robb took official place 1290th (time-based 1274th) 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 25:43 from Muir Woods to Cardiac.
