The UK’s biggest off-road biking event comes to a Northumberland National Park.

The legendary Dirty Reiver challenge will be hosted at Kielder Forest, Northumberland on Saturday, April 22.

More than 1,600 bikers will set off to tackle a single lap of up to 200 kilometres through 63,000 hectare (155,000 acre) using special ‘gravel bikes’ to negotiate tracks, hills and valleys.

Also taking part will be ex Tour de France riders, including Chris Boardman, former Olympic pursuit champion and now England’s first ever Cycling and Walking Commissioner.

“Having ridden a bike personally, professionally and for fitness for more than 50 years, it’s truly wonderful that it’s still possible to keep discovering new ways to use this marvellous machine," Chris explains.

"Gravel riding for me is the exciting sweet spot that sits beautifully between mountain biking and road riding.

"Whilst road riding is still an enjoyable way to explore, dealing with traffic isn’t something anyone enjoys. Gravel meets my needs perfectly: no traffic and a bit of personal challenge all wrapped in spectacular surroundings. It’s where I feel at home.”

A special E-bikes category has also been created for the first time and a team of eight disabled bikers, working with the national Experience Community group, will use specially adapted bikes – mostly hand pedalled – to take on the challenge of a 60 kilometre lap.

Craig Grimes, from Experience Community, said: “It’s fantastic that the Dirty Reiver will have adaptive riders taking part for the first time this year. The equality of access to events such as these for disabled people is so important so that we can also enjoy these amazing trails.”

Kielder is regarded as the UK’s spiritual home of gravel biking and now funding of £150,000 from Northumberland County Council is set to strengthen that reputation.  

Alex Maclennan, Recreation, Public Affairs Manager Northumberland with Forestry England, added: “The Dirty Reiver event has really stoked our ambitions.

"This project will help pay for routes to be created and waymarked giving bikers, or indeed horse riders and walkers, confidence they can navigate even in the remotest spots. 

"In Kielder we have a massive asset which is the 1,000 miles of forest roads.  That’s as far as Land’s End to John O’Groats.

"It can transport people away from roads and traffic and into the wilds. That underlines our message that the nation’s forests are here for everyone to enjoy.”
