Interpretation
Christopher (X-INV) started at 8:22 AM; Michael (U-INV) started at 8:19 AM. That gave Michael a 3 minutes head start on Christopher. On foot, Christopher ran 1:08:25 and Michael ran 1:11:15 — Christopher was 2:50 faster than Michael. Christopher took official place 296th (time-based 270th) and Michael took official place 293rd (time-based 356th).
