There's gonna be a big trail day the Bank Holiday Monday before the race to get the course into shape. Come along and you can fill in that hole which is ruining your flow, berm up a corner for extra speed, or fashion a rock garden to knock your competitors into the bushes. 
All tools and materials are supplied and we're also laying on food, plus some freebies, for everyone who comes out.
