Andrew (Y-INV) started at 8:23 AM; Jonina (P-INV) started at 8:15 AM. That gave Jonina a 8 minutes head start on Andrew. On foot, Andrew ran 1:12:19 and Jonina ran 1:20:10 — Andrew was 7:51 faster than Jonina. Andrew took official place 450th (time-based 401st) and Jonina took official place 447th (time-based 651st).
