Interpretation
Henry (T-INV) started at 8:18 AM; George (AA-INV) started at 8:01 AM. That gave George a 17 minutes head start on Henry. On foot, Henry ran 1:16:22 and George ran 1:33:11 — Henry was 16:49 faster than George. Henry took official place 425th (time-based 535th) and George took official place 422nd (time-based 967th).
