Interpretation
Emily (P-DR) started at 8:42 AM; Alden (L-INV) started at 8:12 AM. That gave Alden a 30 minutes head start on Emily because the Runner wave starts 27 minutes after the Invitational wave. On foot, Emily ran 1:03:00 and Alden ran 1:32:22 — Emily was 29:22 faster than Alden. Emily took official place 523rd (time-based 135th) and Alden took official place 519th (time-based 951st). Alden's head start was enough to flip the official order even though Emily was faster on foot. Biggest swing: Emily gained 15:51 from Muir Woods to Cardiac.
