Interpretation
Jan (V-INV) started at 8:20 AM; Emily (P-INV) started at 8:15 AM. That gave Emily a 5 minutes head start on Jan. On foot, Jan ran 1:10:26 and Emily ran 1:15:16 — Jan was 4:50 faster than Emily. Jan took official place 298th (time-based 339th) and Emily took official place 294th (time-based 494th). Emily's head start was enough to flip the official order even though Jan was faster on foot. Biggest swing: Jan gained 2:47 from Muir Woods to Cardiac.
