Interpretation
Carolyn (Q-INV) started at 8:16 AM; Alan (L-INV) started at 8:12 AM. That gave Alan a 4 minutes head start on Carolyn. On foot, Carolyn ran 1:02:01 and Alan ran 1:05:26 — Carolyn was 3:25 faster than Alan. Carolyn took official place 36th (time-based 113th) and Alan took official place 32nd (time-based 192nd). Alan's head start was enough to flip the official order even though Carolyn was faster on foot. Biggest swing: Carolyn gained 1:15 from Muir Woods to Cardiac.
