Amy (G-DR) started at 8:35 AM; Preston (Q-DR) started at 8:43 AM. That gave Amy a 8 minutes head start on Preston. On foot, Amy ran 1:38:34 and Preston ran 1:30:55 — Preston was 7:39 faster than Amy. Amy took official place 922nd (time-based 1075th) and Preston took official place 926th (time-based 924th). Amy's head start was enough to flip the official order even though Preston was faster on foot. Biggest swing: Preston gained 2:38 from Muir Woods to Cardiac.
