Interpretation
Jordan (M-DR) started at 8:40 AM; Dave (K-DR) started at 8:38 AM. That gave Dave a 2 minutes head start on Jordan. On foot, Jordan ran 1:15:26 and Dave ran 1:16:57 — Jordan was 1:31 faster than Dave. Jordan took official place 582nd (time-based 500th) and Dave took official place 579th (time-based 551st).
