Interpretation
Rachael (P-DR) started at 8:42 AM; Bruce (K-DR) started at 8:38 AM. That gave Bruce a 4 minutes head start on Rachael. On foot, Rachael ran 2:03:53 and Bruce ran 2:07:49 — Rachael was 3:56 faster than Bruce. Rachael took official place 1321st (time-based 1305th) and Bruce took official place 1320th (time-based 1323rd). Bruce's head start was enough to flip the official order even though Rachael was faster on foot. Biggest swing: Rachael gained 6:02 from Muir Woods to Cardiac.
