Interpretation
Jonah (Z-DR) started at 8:51 AM; Collin (Y-DR) started at 8:50 AM. That gave Collin a 1 minute head start on Jonah. On foot, Jonah ran 1:01:22 and Collin ran 1:02:21 — Jonah was 0:59 faster than Collin. Jonah took official place 561st (time-based 92nd) and Collin took official place 560th (time-based 119th).
