Interpretation
Alex (Z-INV) started at 8:24 AM; Cole (T-INV) started at 8:18 AM. That gave Cole a 6 minutes head start on Alex. On foot, Alex ran 1:06:59 and Cole ran 1:12:54 — Alex was 5:55 faster than Cole. Alex took official place 316th (time-based 231st) and Cole took official place 312th (time-based 420th). Cole's head start was enough to flip the official order even though Alex was faster on foot.
