Interpretation
Liz (Q-DR) started at 8:43 AM; Samantha (N-DR) started at 8:41 AM. That gave Samantha a 2 minutes head start on Liz. On foot, Liz ran 1:27:34 and Samantha ran 1:29:33 — Liz was 1:59 faster than Samantha. Liz took official place 850th (time-based 853rd) and Samantha took official place 848th (time-based 896th). Samantha's head start was enough to flip the official order even though Liz was faster on foot. Biggest swing: Liz gained 1:49 from Muir Woods to Cardiac.
