Interpretation
Cindy (Q-DR) started at 8:43 AM; Amy (P-DR) started at 8:42 AM. That gave Amy a 1 minute head start on Cindy. On foot, Cindy ran 1:33:47 and Amy ran 1:34:42 — Cindy was 0:55 faster than Amy. Cindy took official place 1011th (time-based 984th) and Amy took official place 1006th (time-based 1003rd). Amy's head start was enough to flip the official order even though Cindy was faster on foot. Biggest swing: Cindy gained 3:08 from Muir Woods to Cardiac.
