Craig (U-INV) started at 8:19 AM; Alex (X-INV) started at 8:22 AM. That gave Craig a 3 minutes head start on Alex. On foot, Craig ran 1:09:38 and Alex ran 1:06:46 — Alex was 2:52 faster than Craig. Craig took official place 239th (time-based 311th) and Alex took official place 244th (time-based 223rd). Craig's head start was enough to flip the official order even though Alex was faster on foot.
