Well, it depends what you like, but there are loads of small singletrack trails all over the woods north of Notts, the vast majority of which are cheeky and you just have to find them. But saying that, there are some fun bridleways as well…
Spend a while riding around Blidworth, Sansom and Theives Woods and you’ll find it eventually, just try diving down anything that looks interesting! Bestwood has some trails which are easier to find, along with a little jump spot (although I have a feeling this might have been fenced in) and some drops…
It’s always a good area for a night ride, with plenty to keep you interested, but in general I’d head out to the Peak for any kind of day ride…
