Interpretation
Naomi (Q-DR) started at 8:43 AM; Katherine (N-DR) started at 8:41 AM. That gave Katherine a 2 minutes head start on Naomi. On foot, Naomi ran 1:23:03 and Katherine ran 1:24:47 — Naomi was 1:44 faster than Katherine. Naomi took official place 739th (time-based 741st) and Katherine took official place 734th (time-based 787th).
