Kimberworth has a very nice 4X track in sheffield which is good for mountain bikes and BMX. We rode it on MTB and it was a really nice track. The only downside to this place is the wind. It is built on an open field on top of a big hill and the wind can really catch a good rider out if it gets you from the side.
It is made from a very hard sandy gravel which means you can ride in any weather and there are two big berms …
