Interpretation
Jonnie (L-DR) started at 8:39 AM; Johan (X-DR) started at 8:49 AM. That gave Jonnie a 10 minutes head start on Johan. On foot, Jonnie ran 1:46:00 and Johan ran 1:36:16 — Johan was 9:44 faster than Jonnie. Jonnie took official place 1158th (time-based 1179th) and Johan took official place 1162nd (time-based 1037th).
