Interpretation
Alex (Y-DR) started at 8:50 AM; Richard (AA-DR) started at 8:28 AM. That gave Richard a 22 minutes head start on Alex. On foot, Alex ran 1:09:44 and Richard ran 1:31:25 — Alex was 21:41 faster than Richard. Alex took official place 633rd (time-based 314th) and Richard took official place 629th (time-based 933rd). Richard's head start was enough to flip the official order even though Alex was faster on foot. Biggest swing: Alex gained 7:40 from Muir Woods to Cardiac.
