Wave start 8:48 AM (W-DR)
Athlete B

Interpretation
Michael (W-DR) started at 8:48 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 24 minutes head start on Michael because the Runner wave starts 27 minutes after the Invitational wave. On foot, Michael ran 1:40:30 and Edward ran 48:29 — Edward was 52:01 faster than Michael. Michael took official place 1202nd (time-based 1102nd) 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 18:23 from Muir Woods to Cardiac.
