Interpretation

On foot, Ryan ran 1:18:28 and Richie ran 1:19:06 — Ryan was 0:38 faster than Richie. Ryan took official place 843rd (time-based 591st) and Richie took official place 838th (time-based 621st). Richie's head start was enough to flip the official order even though Ryan was faster on foot. Biggest swing: Ryan gained 1:29 from Muir Woods to Cardiac.
