Athlete B

Official

Adam G Shapiro

#689 · 1:11:20 · M25 · Group SCR · DR

Wave start 8:52 AM (SCR-DR)

Interpretation

Duncan (P-DR) started at 8:42 AM; Adam (SCR-DR) started at 8:52 AM. That gave Duncan a 10 minutes head start on Adam. On foot, Duncan ran 1:21:09 and Adam ran 1:11:20 — Adam was 9:49 faster than Duncan. Duncan took official place 686th (time-based 682nd) and Adam took official place 689th (time-based 360th). Duncan's head start was enough to flip the official order even though Adam was faster on foot. Biggest swing: Adam gained 5:16 from Muir Woods to Cardiac.
