On foot, Susan ran 1:49:55 and Edward ran 48:29 — Edward was 1:01:26 faster than Susan. Susan took official place 1190th (time-based 1226th) 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 24:45 from Muir Woods to Cardiac.
