For those that do not know, Moelfre is about 100miles away (so easy in a day trip), the track contains about 1 tree but is flat out and very fun. On a sunny day it is the closest you will get to riding in the alps. You can ride it on any bike, I have been on my hardtail which was only slightly slower than my 224. Uplift is on a tractor trailer and you will get somewhere between 10 and 15 runs.
These uplift days are very low key and open to all, there is no elitism as everyone is there for a good laugh. I have seen 11 year olds on the same trailer as guys who race world cups!

To get you warmed up here is a video of a race there last year...
