I wasn’t that rider, however, there are some great routes over the mendips. Try starting at the bottom of the Cheddar gorge, then go up (you can do Jacobs Ladder, but you’ll walk most of it), turn left at the top through Velvet Bottom, over to the trig point (Black Down I think), from which you can head down towards Christmas trees and Rowbarrow downhills. of Burrington for some sweet singletrack. All of which will put a smile on your face!. From any of the downhills, head back up and you’ll find decent trails before going back over the top, through Velvet and then down Jacobs.
It makes a lot more sense when you look on a map (google the specifics I’ve mentioned), or failing that, fancy a meet up for a ride?
