Sarah (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on Sarah because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sarah ran 1:52:57 and Edward ran 48:29 — Edward was 1:04:28 faster than Sarah. Sarah took official place 1265th (time-based 1250th) 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 23:09 from Muir Woods to Cardiac.
