Interpretation
Sally (Q-DR) started at 8:43 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 19 minutes head start on Sally because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sally ran 1:57:58 and Edward ran 48:29 — Edward was 1:09:29 faster than Sally. Sally took official place 1296th (time-based 1278th) 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 26:29 from Muir Woods to Cardiac.
