Interpretation

Dave (AAA-INV) started at 8:00 AM; Ronn (P-DR) started at 8:42 AM. That gave Dave a 42 minutes head start on Ronn because the Runner wave starts 27 minutes after the Invitational wave. On foot, Dave ran 1:56:44 and Ronn ran 1:14:56 — Ronn was 41:48 faster than Dave. Dave took official place 596th (time-based 1270th) and Ronn took official place 598th (time-based 478th). 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.
