Interpretation

Zach (Y-DR) started at 8:50 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 26 minutes head start on Zach because the Runner wave starts 27 minutes after the Invitational wave. On foot, Zach ran 1:01:08 and Edward ran 48:29 — Edward was 12:39 faster than Zach. Zach took official place 556th (time-based 87th) 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 5:12 from Muir Woods to Cardiac.
