Athlete B

Wave start 8:38 AM (K-DR)
Interpretation
Bonnie (AAA-INV) started at 8:00 AM; Kenedy (K-DR) started at 8:38 AM. That gave Bonnie a 38 minutes head start on Kenedy because the Runner wave starts 27 minutes after the Invitational wave. On foot, Bonnie ran 2:39:42 and Kenedy ran 2:02:01 — Kenedy was 37:41 faster than Bonnie. Bonnie took official place 1285th (time-based 1377th) and Kenedy took official place 1289th (time-based 1298th). Bonnie's head start was enough to flip the official order even though Kenedy was faster on foot. Biggest swing: Kenedy gained 13:37 from Muir Woods to Cardiac.
