Interpretation
Kathryn (Q-DR) started at 8:43 AM; Theresa (M-DR) started at 8:40 AM. That gave Theresa a 3 minutes head start on Kathryn. On foot, Kathryn ran 1:27:47 and Theresa ran 1:30:46 — Kathryn was 2:59 faster than Theresa. Kathryn took official place 858th (time-based 859th) and Theresa took official place 857th (time-based 921st). Theresa's head start was enough to flip the official order even though Kathryn was faster on foot. Biggest swing: Kathryn gained 2:00 from Cardiac to White Gate.
