Interpretation
Christopher (P-INV) started at 8:15 AM; Michael (K-INV) started at 8:11 AM. That gave Michael a 4 minutes head start on Christopher. On foot, Christopher ran 1:16:30 and Michael ran 1:20:19 — Christopher was 3:49 faster than Michael. Christopher took official place 340th (time-based 539th) and Michael took official place 335th (time-based 657th).
