On foot, Grace ran 1:32:42 and Edward ran 48:29 — Edward was 44:13 faster than Grace. Grace took official place 854th (time-based 957th) 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 18:52 from Muir Woods to Cardiac.
