Interpretation
Sally (Q-DR) started at 8:43 AM; Marci (P-DR) started at 8:42 AM. That gave Marci a 1 minute head start on Sally. On foot, Sally ran 1:57:58 and Marci ran 1:58:23 — Sally was 0:25 faster than Marci. Sally took official place 1296th (time-based 1278th) and Marci took official place 1292nd (time-based 1280th). Marci's head start was enough to flip the official order even though Sally was faster on foot. Biggest swing: Marci gained 3:48 from Muir Woods to Cardiac.
