About Dirty Reiver

The ride takes place in Kielder Forest. 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 events are NOT races. However, finishing times will be graded and these grades are detailed in finishing times on the event page.

The event is based at the Kielder Castle Forest Park Centre, Kielder, Hexham, Northumberland NE48 1ER.

Event HQ will open at noon on Friday 25 April with overnight camping available.

This is a challenge not a race. Riders can choose from the Dirty Reiver (200km), the Dirty One Thirty (130km) or the Dirty Sixty Fiver (65km) distance events.
