what do those that do it figure that it takes to do this event, roughly

Id say roughly

in 2003 it was roughly

being half yorkshire ,so i'm tight,i have got round on 500 pounds,same tyres ll week then used the back for a month or two as well but as an average i'd budget for a 1000 and hope you have no major disasters,well worth going though,awesome event.ridden six times entered this year ,may finish when i've done 10 but don't hold me to it.
