Wave start 8:40 AM (M-DR)
Athlete B

Interpretation
Sarah (M-DR) started at 8:40 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 16 minutes head start on Sarah because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sarah ran 1:33:59 and Edward ran 48:29 — Edward was 45:30 faster than Sarah. Sarah took official place 929th (time-based 988th) 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 16:11 from Muir Woods to Cardiac.
