Interpretation
George (H-DR) started at 8:36 AM; Jackson (Z-DR) started at 8:51 AM. That gave George a 15 minutes head start on Jackson. On foot, George ran 1:22:23 and Jackson ran 1:07:34 — Jackson was 14:49 faster than George. George took official place 616th (time-based 716th) and Jackson took official place 617th (time-based 251st).
