Interpretation
Christopher (W-INV) started at 8:21 AM; Tara (Q-DR) started at 8:43 AM. That gave Christopher a 22 minutes head start on Tara because the Runner wave starts 27 minutes after the Invitational wave. On foot, Christopher ran 1:30:05 and Tara ran 1:08:50 — Tara was 21:15 faster than Christopher. Christopher took official place 554th (time-based 914th) and Tara took official place 557th (time-based 284th). Christopher's head start was enough to flip the official order even though Tara was faster on foot. Biggest swing: Tara gained 11:18 from Muir Woods to Cardiac.
