Athlete B

Wave start 8:27 AM (AAA-DR)

Interpretation

Robert (Bob) (AAA-INV) started at 8:00 AM; Ronald (AAA-DR) started at 8:27 AM. That gave Robert (Bob) a 27 minutes head start on Ronald because the Runner wave starts 27 minutes after the Invitational wave. On foot, Robert (Bob) ran 2:48:09 and Ronald ran 2:22:52 — Ronald was 25:17 faster than Robert (Bob). Robert (Bob) took official place 1332nd (time-based 1384th) and Ronald took official place 1335th (time-based 1358th). Robert (Bob)'s head start was enough to flip the official order even though Ronald was faster on foot. Biggest swing: Ronald gained 12:09 from Muir Woods to Cardiac.
