Interpretation
Harold (Hal) (AAA-DR) started at 8:27 AM; Colleen (AAA-INV) started at 8:00 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, Harold (Hal) ran 2:37:48 and Colleen ran 3:01:53 — Harold (Hal) was 24:05 faster than Colleen. Harold (Hal) took official place 1373rd (time-based 1374th) and Colleen took official place 1369th (time-based 1392nd).
