Interpretation
Kathryn (Q-DR) started at 8:43 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 19 minutes head start on Kathryn because the Runner wave starts 27 minutes after the Invitational wave. On foot, Kathryn ran 1:27:47 and Edward ran 48:29 — Edward was 39:18 faster than Kathryn. Kathryn took official place 858th (time-based 859th) 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 15:29 from Muir Woods to Cardiac.
