I'm doing the Fellsman on the same day and will be wearing my INOV8 roclites mainly because I've worn them all winter in snow, mud & bogs and they are more comfortable on long runs than my mudclaws. If it helps, I wore them last year on the 3ps race when it was sunny and dry but also on a recent run of the 3ps when it was wet and boggy and they were very good on both runs. You just need a bit of grip and some shoes that drain well!
