It doesn't matter if he has someone running with him every step of the way until he finished. He won't be a considered a cheater unless there is proof that he lied about is 5:30-6:00 60 mile days.
This needs to be the focus. Nothing else will make the fanboys go away.
He is going to walk the rest of the way, it doesn't prove he covered 70+ miles/day until the halfway mark. You're telling me ran 80 miles in 100+ degree heat in the desert unassisted, in between 70+ mile days?
