Lori (F-DR) started at 8:34 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 10 minutes head start on Lori because the Runner wave starts 27 minutes after the Invitational wave. On foot, Lori ran 2:10:27 and Edward ran 48:29 — Edward was 1:21:58 faster than Lori. Lori took official place 1316th (time-based 1334th) 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 31:24 from Muir Woods to Cardiac.
