Interpretation
Lutz (W-DR) started at 8:48 AM; Mary (L-DR) started at 8:39 AM. That gave Mary a 9 minutes head start on Lutz. On foot, Lutz ran 1:23:41 and Mary ran 1:32:11 — Lutz was 8:30 faster than Mary. Lutz took official place 876th (time-based 759th) and Mary took official place 871st (time-based 948th). Mary's head start was enough to flip the official order even though Lutz was faster on foot. Biggest swing: Lutz gained 3:03 from Muir Woods to Cardiac.
