Follow along as Ollie and Wheeler make their mud run debuts at Saturday’s CIBC Run For Our Lives event in Yellowknife.

Ollie, four-nothing down in this year’s series of head-to-head contests against Wheeler, has the opportunity to begin his comeback if he can battle through to the final obstacle and conquer it ahead of his morning show rival.

The mud run, in its second year and attended by hundreds of people, raises money for cancer services in the NWT.
