Interpretation
Anita (L-DR) started at 8:39 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 15 minutes head start on Anita because the Runner wave starts 27 minutes after the Invitational wave. On foot, Anita ran 2:06:56 and Edward ran 48:29 — Edward was 1:18:27 faster than Anita. Anita took official place 1322nd (time-based 1318th) 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 25:41 from Muir Woods to Cardiac.
