Interpretation
Kathryn (Q-DR) started at 8:43 AM; Grace (K-DR) started at 8:38 AM. That gave Grace a 5 minutes head start on Kathryn. On foot, Kathryn ran 1:27:47 and Grace ran 1:32:42 — Kathryn was 4:55 faster than Grace. Kathryn took official place 858th (time-based 859th) and Grace took official place 854th (time-based 957th). Grace's head start was enough to flip the official order even though Kathryn was faster on foot. Biggest swing: Kathryn gained 3:23 from Muir Woods to Cardiac.
