Interpretation
Mark (Z-DR) started at 8:51 AM; Michael (U-DR) started at 8:46 AM. That gave Michael a 5 minutes head start on Mark. On foot, Mark ran 1:09:26 and Michael ran 1:14:20 — Mark was 4:54 faster than Michael. Mark took official place 645th (time-based 308th) and Michael took official place 641st (time-based 458th).
