Interpretation
Ryan (U-DR) started at 8:46 AM; Kirsti (N-DR) started at 8:41 AM. That gave Kirsti a 5 minutes head start on Ryan. On foot, Ryan ran 1:37:51 and Kirsti ran 1:42:35 — Ryan was 4:44 faster than Kirsti. Ryan took official place 1143rd (time-based 1065th) and Kirsti took official place 1139th (time-based 1131st). Kirsti's head start was enough to flip the official order even though Ryan was faster on foot. Biggest swing: Ryan gained 1:30 from Muir Woods to Cardiac.
