On foot, Michael ran 1:05:40 and Dave ran 1:56:44 — Michael was 51:04 faster than Dave. Michael took official place 595th (time-based 197th) and Dave took official place 596th (time-based 1270th). Michael was faster on foot and finished ahead on the official clock too. Biggest swing: Michael gained 19:09 from Muir Woods to Cardiac.
