Wave start 8:00 AM (AAA-INV)
Athlete B
OfficialCathleen J Staehli
#1286 · 2:12:42 · F76 · Group AAA · DR
Wave start 8:27 AM (AAA-DR)
Interpretation
Bonnie (AAA-INV) started at 8:00 AM; Cathleen (AAA-DR) started at 8:27 AM. That gave Bonnie a 27 minutes head start on Cathleen because the Runner wave starts 27 minutes after the Invitational wave. On foot, Bonnie ran 2:39:42 and Cathleen ran 2:12:42 — Cathleen was 27:00 faster than Bonnie. Bonnie took official place 1285th (time-based 1377th) and Cathleen took official place 1286th (time-based 1339th). Bonnie's head start was enough to flip the official order even though Cathleen was faster on foot. Biggest swing: Cathleen gained 13:44 from Muir Woods to Cardiac.
