Chain Reaction Gritopia powered by Pirelli 2022

Welcome to Chain Reaction Gritopia powered by Pirelli our grit, gravel (or whatever you want to call it), adventure.

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!

About The Course

We’re still confirming this year’s course with the relevant landowners and authorities, but it’s set to be a very enjoyable tour visiting some less-travelled corners of the Tweed Valley. The distance and ascent figures will be roughly inline with previous events. You can download all the info from the 2018, 2019 and 2021 events to get all the info and maps for those courses. Some sections of those events are likely to be repeated.
