Interpretation
Colleen (AAA-INV) started at 8:00 AM; Harold (Hal) (AAA-DR) started at 8:27 AM. That gave Colleen a 27 minutes head start on Harold (Hal) because the Runner wave starts 27 minutes after the Invitational wave. On foot, Colleen ran 3:01:53 and Harold (Hal) ran 2:37:48 — Harold (Hal) was 24:05 faster than Colleen. Colleen took official place 1369th (time-based 1392nd) and Harold (Hal) took official place 1373rd (time-based 1374th). Colleen's head start was enough to flip the official order even though Harold (Hal) was faster on foot. Biggest swing: Harold (Hal) gained 8:44 from Muir Woods to Cardiac.
