Interpretation
Sarah (L-DR) started at 8:39 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 15 minutes head start on Sarah because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sarah ran 1:33:36 and Edward ran 48:29 — Edward was 45:07 faster than Sarah. Sarah took official place 902nd (time-based 976th) 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 17:02 from Muir Woods to Cardiac.
