After definately not riding a bike on some peaty boggy bits on the PW yesterday, i wondered if someone were to ride this type of trail, would a fatbike be a better bet for floating over foot deep sections of spoooge or would it still be waste of time?

Fatties float fine, have a look at some of the old pics of stuff the epicyclo used to ride over on his

I ride some pretty muddy stuff on my fatty. The fat tyres float over it rather than cut through it like thinner tyres.
