Gregg (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on Gregg because the Runner wave starts 27 minutes after the Invitational wave. On foot, Gregg ran 1:21:39 and Edward ran 48:29 — Edward was 33:10 faster than Gregg. Gregg took official place 693rd (time-based 696th) 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 13:55 from Muir Woods to Cardiac.
