Interpretation
Todd (P-DR) started at 8:42 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 18 minutes head start on Todd because the Runner wave starts 27 minutes after the Invitational wave. On foot, Todd ran 1:30:58 and Edward ran 48:29 — Edward was 42:29 faster than Todd. Todd took official place 909th (time-based 925th) 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 18:07 from Muir Woods to Cardiac.
