Interpretation
Sharon (AAA-DR) started at 8:27 AM; Bonnie (AAA-INV) started at 8:00 AM. That gave Bonnie a 27 minutes head start on Sharon because the Runner wave starts 27 minutes after the Invitational wave. On foot, Sharon ran 2:10:21 and Bonnie ran 2:39:42 — Sharon was 29:21 faster than Bonnie. Sharon took official place 1280th (time-based 1333rd) and Bonnie took official place 1285th (time-based 1377th). Sharon was faster on foot and finished ahead on the official clock too. Biggest swing: Sharon gained 7:55 from Cardiac to White Gate.
