Wave start 8:46 AM (U-DR)
Athlete B

Interpretation
John (U-DR) started at 8:46 AM; Edward (Z-INV) started at 8:24 AM. That gave Edward a 22 minutes head start on John because the Runner wave starts 27 minutes after the Invitational wave. On foot, John ran 1:28:53 and Edward ran 48:29 — Edward was 40:24 faster than John. John took official place 950th (time-based 884th) 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 14:28 from Muir Woods to Cardiac.
