This place is a mountain that has many tracks carved into it for the pleasure of mountain bikers. It's also a brutal cardiovascular workout. If you think you are running fit (which I thought I was) then try this. I was invited to go here by some mates at work after getting my new bike but before that I put in some mileage in the the Snowdon Mountain Range with a good friend last weekend. We did a 30 mile/hilly/wet ride and I loved every minute of it. So I prepared well for this course. There is a choice of 3 runs just like skiing routes blue, red and black with the latter being the most challenging route in terms of technical and physical ability. The lads after seeing me do a bit of the red route said I should be OK on the black so off we went. Brutal! Is a perfect word to describe how it was. Thoroughly exhilarating and completely physically demanding. It was fantastic. You can go at any pace but it is safer to go at good speed so your tyres just fly over the numerous rocks and boulders. The steep turns and unrelenting bumps and humps keep you focused and alert throughout the ride. If you ever find yourself in North Wales and have a mountain bike this is a must.
