Interpretation

Jon (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Jon because the Runner wave starts 27 minutes after the Invitational wave. On foot, Jon ran 1:21:30 and Edward ran 48:29 — Edward was 33:01 faster than Jon. Jon took official place 873rd (time-based 693rd) 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 14:45 from Muir Woods to Cardiac.
