Interpretation
Anne-Charlotte (Q-INV) started at 8:16 AM; Zach (Y-DR) started at 8:50 AM. That gave Anne-Charlotte a 34 minutes head start on Zach because the Runner wave starts 27 minutes after the Invitational wave. On foot, Anne-Charlotte ran 1:34:59 and Zach ran 1:01:08 — Zach was 33:51 faster than Anne-Charlotte. Anne-Charlotte took official place 551st (time-based 1009th) and Zach took official place 556th (time-based 87th). Anne-Charlotte's head start was enough to flip the official order even though Zach was faster on foot. Biggest swing: Zach gained 12:27 from Muir Woods to Cardiac.
