Interpretation
Rachael (P-DR) started at 8:42 AM; Lori (F-DR) started at 8:34 AM. That gave Lori a 8 minutes head start on Rachael. On foot, Rachael ran 2:03:53 and Lori ran 2:10:27 — Rachael was 6:34 faster than Lori. Rachael took official place 1321st (time-based 1305th) and Lori took official place 1316th (time-based 1334th). Lori's head start was enough to flip the official order even though Rachael was faster on foot. Biggest swing: Rachael gained 6:53 from Muir Woods to Cardiac.
