Interpretation
Carolyn (Q-INV) started at 8:16 AM; Sean (Z-INV) started at 8:24 AM. That gave Carolyn a 8 minutes head start on Sean. On foot, Carolyn ran 1:02:01 and Sean ran 54:23 — Sean was 7:38 faster than Carolyn. Carolyn took official place 36th (time-based 113th) and Sean took official place 37th (time-based 14th). Carolyn's head start was enough to flip the official order even though Sean was faster on foot. Biggest swing: Sean gained 3:26 from Muir Woods to Cardiac.
