Interpretation
Daniel (N-DR) started at 8:41 AM; Brian (U-DR) started at 8:46 AM. That gave Daniel a 5 minutes head start on Brian. On foot, Daniel ran 1:19:07 and Brian ran 1:14:23 — Brian was 4:44 faster than Daniel. Daniel took official place 638th (time-based 622nd) and Brian took official place 643rd (time-based 459th).
