On foot, Becca ran 1:20:42 and Edward ran 48:29 — Edward was 32:13 faster than Becca. Becca took official place 678th (time-based 667th) and Edward took official place 2nd (time-based 1st). Edward was faster on foot and finished ahead on the official clock too. Biggest swing: Edward gained 12:41 from Muir Woods to Cardiac.
