Was thinking that but meh. You have a new club starting up in norwich. Adam's organising it so get in touch with him. Other than that take a look on uk bike trial and bike trial uk and find a club local to you. (essex at a guess). The its just a case of ringing up and filling out the forms you get sent. The colours refer to the route. White-novice, blue-intermediate, red-expert, yellow-elite. You'll prob wanna start in blue and go from there. Matt
