Interpretation
Alena (Q-INV) started at 8:16 AM; Henry (T-INV) started at 8:18 AM. That gave Alena a 2 minutes head start on Henry. On foot, Alena ran 1:18:11 and Henry ran 1:16:22 — Henry was 1:49 faster than Alena. Alena took official place 421st (time-based 584th) and Henry took official place 425th (time-based 535th).
