Interpretation
James (Y-DR) started at 8:50 AM; Tom (V-DR) started at 8:47 AM. That gave Tom a 3 minutes head start on James. On foot, James ran 1:35:31 and Tom ran 1:38:14 — James was 2:43 faster than Tom. James took official place 1164th (time-based 1024th) and Tom took official place 1161st (time-based 1071st).
