Bruce (K-DR) started at 8:38 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 14 minutes head start on Bruce because the Runner wave starts 27 minutes after the Invitational wave. On foot, Bruce ran 2:07:49 and Edward ran 48:29 — Edward was 1:19:20 faster than Bruce. Bruce took official place 1320th (time-based 1323rd) 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 30:33 from Muir Woods to Cardiac.
