Interpretation
Zach (Z-DR) started at 8:51 AM; Jon (Y-DR) started at 8:50 AM. That gave Jon a 1 minute head start on Zach. On foot, Zach ran 1:20:32 and Jon ran 1:21:30 — Zach was 0:58 faster than Jon. Zach took official place 874th (time-based 663rd) and Jon took official place 873rd (time-based 693rd). Jon's head start was enough to flip the official order even though Zach was faster on foot. Biggest swing: Zach gained 2:09 from Muir Woods to Cardiac.
