Interpretation
Colleen (AAA-INV) started at 8:00 AM; Christopher (X-DR) started at 8:49 AM. That gave Colleen a 49 minutes head start on Christopher because the Runner wave starts 27 minutes after the Invitational wave. On foot, Colleen ran 3:01:53 and Christopher ran 2:14:03 — Christopher was 47:50 faster than Colleen. Colleen took official place 1369th (time-based 1392nd) and Christopher took official place 1372nd (time-based 1341st). Colleen's head start was enough to flip the official order even though Christopher was faster on foot. Biggest swing: Christopher gained 16:24 from Muir Woods to Cardiac.
