The Dirty Reiver 200 (200km) and Dirty One Thirty (130km) are off road cycling challenges based on the Gravel Grinder format found predominantly in the mid west of America.
Riders will traverse gravel forest access roads that service the vast areas of forest covering the border region of England and Scotland. The events will take riders through remote areas providing outstanding viewpoints across this spectacular part of the UK.
Due to the shared use of some of the course the Dirty Reiver and Dirty One Thirty are NOT races. However, finishing times will be graded and these grades are detailed in finishing times on the event page.
