Interpretation
Laura (Q-DR) started at 8:43 AM; Ben (Y-DR) started at 8:50 AM. That gave Laura a 7 minutes head start on Ben. On foot, Laura ran 1:34:42 and Ben ran 1:27:42 — Ben was 7:00 faster than Laura. Laura took official place 1034th (time-based 1002nd) and Ben took official place 1035th (time-based 855th).
