Interpretation
Eric (W-DR) started at 8:48 AM; Emily (Q-DR) started at 8:43 AM. That gave Emily a 5 minutes head start on Eric. On foot, Eric ran 1:28:49 and Emily ran 1:33:48 — Eric was 4:59 faster than Emily. Eric took official place 1015th (time-based 879th) and Emily took official place 1013th (time-based 985th).
