that a lot better example,but as you see it cut in the earth,so you get the gradients,which make the track so much better,than the on top of the earth tracks,but take a lot more work to build and a lot more maintence.but that more like a good track,why not look at coventy and westmill,your only down the road from clanfields,if you want to put on races see what outher people expect and what they pay for at a weekend?and if you want a brac track ask them about the legal track lenght ect
have you seen the free lap software,you just push the number on the laptop every time you go past,it could get you lot started till you get the funds for the my laps kit.
