Interpretation
Emily (Q-DR) started at 8:43 AM; Jakob (V-DR) started at 8:47 AM. That gave Emily a 4 minutes head start on Jakob. On foot, Emily ran 1:33:48 and Jakob ran 1:29:49 — Jakob was 3:59 faster than Emily. Emily took official place 1013th (time-based 985th) and Jakob took official place 1014th (time-based 907th).
