It's hard to know how to translate road running training ideas to fell. Personally I think fell running requires more overall strength, arms,back and core as well as legs.

Overtraining is a real danger too as I found to my peril this year. Too many long races basically ruined me I was at the back of the field at one point after almost being in the top third at the start of the year.

Long races especially Lakeland Classics extract a toll on your entire body and I made the mistake of trying to do speed sessions straight after them! You start to get slower so you train a bit more and it becomes a vicious cycle until you struggle sleeping and have to stop completely.

Maybe it was a virus and not overtraining, but it's made me look at my training in a whole different way. To be honest with you it was a struggle not to give up.
