Interpretation
Christopher (Y-INV) started at 8:23 AM; Rob (T-INV) started at 8:18 AM. That gave Rob a 5 minutes head start on Christopher. On foot, Christopher ran 1:10:19 and Rob ran 1:15:07 — Christopher was 4:48 faster than Rob. Christopher took official place 399th (time-based 335th) and Rob took official place 394th (time-based 485th).
