Interpretation
Zach (Y-DR) started at 8:50 AM; Christopher (W-INV) started at 8:21 AM. That gave Christopher a 29 minutes head start on Zach because the Runner wave starts 27 minutes after the Invitational wave. On foot, Zach ran 1:01:08 and Christopher ran 1:30:05 — Zach was 28:57 faster than Christopher. Zach took official place 556th (time-based 87th) and Christopher took official place 554th (time-based 914th). Christopher's head start was enough to flip the official order even though Zach was faster on foot. Biggest swing: Zach gained 11:58 from Muir Woods to Cardiac.
