The Panaracer Dirty Reiver (200km), Dirty One Thirty (130km) and the Dirty Sixty Fiver (65km) are off road cycling challenges based on the Gravel Grinder format found predominantly in America.

The ‘Sixty Fiver’ course will also be open to E-Bikes as the Dirt-E-Reiver! 

2025 courses will be re-planned to include a new start.

Riders will traverse 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.
