Interpretation
Alice (Q-DR) started at 8:43 AM; Jason (V-DR) started at 8:47 AM. That gave Alice a 4 minutes head start on Jason. On foot, Alice ran 1:33:29 and Jason ran 1:29:37 — Jason was 3:52 faster than Alice. Alice took official place 999th (time-based 973rd) and Jason took official place 1002nd (time-based 900th).
