Interpretation
Alice (Q-DR) started at 8:43 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 19 minutes head start on Alice because the Runner wave starts 27 minutes after the Invitational wave. On foot, Alice ran 1:33:29 and Edward ran 48:29 — Edward was 45:00 faster than Alice. Alice took official place 999th (time-based 973rd) 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 18:27 from Muir Woods to Cardiac.
