Wave start 8:43 AM (Q-DR)

Athlete B

Official

Bonnie A Sullivan

#1285 · 2:39:42 · F73 · Group AAA · INV

Wave start 8:00 AM (AAA-INV)

Interpretation

Graciela (Q-DR) started at 8:43 AM; Bonnie (AAA-INV) started at 8:00 AM. That gave Bonnie a 43 minutes head start on Graciela because the Runner wave starts 27 minutes after the Invitational wave. On foot, Graciela ran 1:56:48 and Bonnie ran 2:39:42 — Graciela was 42:54 faster than Bonnie. Graciela took official place 1287th (time-based 1271st) and Bonnie took official place 1285th (time-based 1377th). Bonnie's head start was enough to flip the official order even though Graciela was faster on foot. Biggest swing: Graciela gained 13:20 from Muir Woods to Cardiac.
