Went for a little trip to Cwm Carn today in South Wales. Its fantastic! By far that best mountain biking trail I have done to date, very long up hill - about 4 miles and very technical (there is a transport service to the top if you book in advance) but the downhill is bloody awesome! Although I think I found the limits of the hardtail today and at points I thought I was lucky to get down in one piece.
My chain went twice (bit of a bummer) and a friends went a couple of times well, we also had a puncture - so lots of mountain pitstops Out of 7 of us thats a fair bit to go wrong
Great day out and well worth the effort, get yourself down there! Link below
If you search for Cwm Carn on you tube you will find loads of vids of the trails there - very cool stuff indeed
Just got to find some time to go again! - ah and look at new bikes for in the new year
