Interpretation
Kim (M-DR) started at 8:40 AM; Sarah (Q-INV) started at 8:16 AM. That gave Sarah a 24 minutes head start on Kim because the Runner wave starts 27 minutes after the Invitational wave. On foot, Kim ran 1:10:40 and Sarah ran 1:33:57 — Kim was 23:17 faster than Sarah. Kim took official place 548th (time-based 344th) and Sarah took official place 546th (time-based 987th). Sarah's head start was enough to flip the official order even though Kim was faster on foot. Biggest swing: Kim gained 9:25 from Muir Woods to Cardiac.
