Interpretation

Ronn (P-DR) started at 8:42 AM; Dave (AAA-INV) started at 8:00 AM. That gave Dave a 42 minutes head start on Ronn because the Runner wave starts 27 minutes after the Invitational wave. On foot, Ronn ran 1:14:56 and Dave ran 1:56:44 — Ronn was 41:48 faster than Dave. Ronn took official place 598th (time-based 478th) and Dave took official place 596th (time-based 1270th). Dave's head start was enough to flip the official order even though Ronn was faster on foot. Biggest swing: Ronn gained 14:18 from Muir Woods to Cardiac.
