Interpretation
Anita (L-DR) started at 8:39 AM; Bruce (K-DR) started at 8:38 AM. That gave Bruce a 1 minute head start on Anita. On foot, Anita ran 2:06:56 and Bruce ran 2:07:49 — Anita was 0:53 faster than Bruce. Anita took official place 1322nd (time-based 1318th) and Bruce took official place 1320th (time-based 1323rd). Bruce's head start was enough to flip the official order even though Anita was faster on foot. Biggest swing: Anita gained 4:52 from Muir Woods to Cardiac.
