If you get the chance to watch it check out the guy coming down the Glen river route. Flat out madness.
They travel at some speed, looks mental.
looks very well made, if only they would make a ski lift up donard ::) i'd love to have a go at that stuff, couldn't be arsed cycling up the hil first though, fair play to those that do though
