Rider Notes 2022

Route 2022

Results 2022

Chain Reaction Gritopia powered by Pirelli will take you on a journey deep into the valley hinterland, leaving the traffic far behind, and often far below you. Expect mile after mile of empty grit and gravel with a few stretches of quiet tarmac linking it all up. The full course is approx 75km (TBC) but shorter options are always available.

Any suitable bike will do. A dedicated gravel bike is perfect but a mountain bike will be fine. Oh, and eBikes are welcome! We don’t however recommend a road bike, they’ll be a tad uncomfortable, prone to puncture and the gearing might by unhelpful in places!
