I had never heard of the place until yesterday - but I travelled down to Bodmin in Cornwall to ride Cardinham Woods. Its a blue route with two red loops off it (The Hells Teeth climb is bloody steep). I felt it was a bit more than just a blue, but whatever, it is a fantastic track. Approx 7 miles in total but you can also ride to the nearby Lanhydrock where there are a few more blue routes and red dual slalom. Certainly the best days riding I've had in a while - I did it 3 times before the light gave out! Check it out if you get the chance.
