Interpretation
Alyssa (Q-DR) started at 8:43 AM; Shelby (L-DR) started at 8:39 AM. That gave Shelby a 4 minutes head start on Alyssa. On foot, Alyssa ran 1:36:32 and Shelby ran 1:40:29 — Alyssa was 3:57 faster than Shelby. Alyssa took official place 1070th (time-based 1048th) and Shelby took official place 1069th (time-based 1101st). Shelby's head start was enough to flip the official order even though Alyssa was faster on foot. Biggest swing: Alyssa gained 5:50 from Muir Woods to Cardiac.
