Did anyone else see this on Look North tonight? One for those who don't mind getting dirty. A 75 mile circular loop in Lincolnshire (sort of centered around Horncastle)all on quiet country lanes and briddleways. For further info see these links

Might make a good challenge as a mammoth mtb/cross bike* day ride later on in the year?
