Interpretation
Kirsti (N-DR) started at 8:41 AM; Ryan (U-DR) started at 8:46 AM. That gave Kirsti a 5 minutes head start on Ryan. On foot, Kirsti ran 1:42:35 and Ryan ran 1:37:51 — Ryan was 4:44 faster than Kirsti. Kirsti took official place 1139th (time-based 1131st) and Ryan took official place 1143rd (time-based 1065th).
