Interpretation
Christopher (P-INV) started at 8:15 AM; Jaclyn (M-INV) started at 8:13 AM. That gave Jaclyn a 2 minutes head start on Christopher. On foot, Christopher ran 1:16:30 and Jaclyn ran 1:18:24 — Christopher was 1:54 faster than Jaclyn. Christopher took official place 340th (time-based 539th) and Jaclyn took official place 338th (time-based 590th). Jaclyn's head start was enough to flip the official order even though Christopher was faster on foot. Biggest swing: Christopher gained 1:46 from Muir Woods to Cardiac.
