Interpretation
Jon (Y-DR) started at 8:50 AM; Matthew (X-DR) started at 8:49 AM. That gave Matthew a 1 minute head start on Jon. On foot, Jon ran 1:10:43 and Matthew ran 1:11:39 — Jon was 0:56 faster than Matthew. Jon took official place 649th (time-based 347th) and Matthew took official place 647th (time-based 377th).
