Interpretation
Arianna (Q-DR) started at 8:43 AM; Megan (L-INV) started at 8:12 AM. That gave Megan a 31 minutes head start on Arianna because the Runner wave starts 27 minutes after the Invitational wave. On foot, Arianna ran 1:05:09 and Megan ran 1:34:16 — Arianna was 29:07 faster than Megan. Arianna took official place 534th (time-based 184th) and Megan took official place 530th (time-based 994th). Megan's head start was enough to flip the official order even though Arianna was faster on foot. Biggest swing: Arianna gained 9:58 from Muir Woods to Cardiac.
