On foot, Lloyd ran 2:27:11 and Susan ran 1:49:55 — Susan was 37:16 faster than Lloyd. Lloyd took official place 1194th (time-based 1363rd) and Susan took official place 1190th (time-based 1226th). Susan was faster on foot and finished ahead on the official clock too. Biggest swing: Susan gained 10:34 from Muir Woods to Cardiac.
