Wave start 8:33 AM (E-DR)
Athlete B
OfficialBonnie A Sullivan
#1285 · 2:39:42 · F73 · Group AAA · INV
Wave start 8:00 AM (AAA-INV)
Interpretation
Polly (E-DR) started at 8:33 AM; Bonnie (AAA-INV) started at 8:00 AM. That gave Bonnie a 33 minutes head start on Polly because the Runner wave starts 27 minutes after the Invitational wave. On foot, Polly ran 2:07:01 and Bonnie ran 2:39:42 — Polly was 32:41 faster than Bonnie. Polly took official place 1288th (time-based 1320th) and Bonnie took official place 1285th (time-based 1377th). Bonnie's head start was enough to flip the official order even though Polly was faster on foot. Biggest swing: Polly gained 13:33 from Muir Woods to Cardiac.
