Wave start 8:52 AM (SCR-DR)
Athlete B

Interpretation
Adam (SCR-DR) started at 8:52 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 28 minutes head start on Adam because the Runner wave starts 27 minutes after the Invitational wave. On foot, Adam ran 1:11:20 and Edward ran 48:29 — Edward was 22:51 faster than Adam. Adam took official place 689th (time-based 360th) 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 9:12 from Muir Woods to Cardiac.
