Finish your mountain biking season with an unforgettable challenge: The Christmas Beast of Llangollen. This grueling endurance ride through North Wales' Ceiriog Valley is designed for those who seek more than just smooth trails and easy climbs. The full course spans approximately 42 kilometers, packed with relentless ascents totaling around 1,400 meters (4,600 feet). You'll face the notorious "Six Lumps," a series of brutal climbs that will test your limits. Each summit rewards you with stunning views over rugged landscapes and moorland. For those looking for a less daunting option, there's also a shorter 25-kilometer route available. The terrain is varied and challenging, featuring quiet country lanes, rough bridleways, steep gravel ascents, and exposed stretches of open land. The late-autumn setting in the Welsh hills adds an extra layer of adventure to this already intense ride. While you can tackle this beast solo or with friends, it's also a chance to embrace the festive spirit through fancy dress competitions for both riders and bikes. Prizes will be awarded to the most creatively decorated participants. A detailed GPX route file is provided to help navigate the challenging terrain effectively. Participants are advised to bring their smartphones or GPS devices equipped with navigation apps. This event isn’t just a ride—it’s an experience that pushes your limits in one of Wales' most iconic mountain biking regions. Are you ready for The Beast? Registration includes optional XCover insurance, allowing participants to receive refunds if they're unable to attend due to unforeseen circumstances. Join us and see if you have what it takes to conquer the Christmas Beast of Llangollen this holiday season.

About Llangollen
Learn more about the host city, Llangollen.
Llangollen is a small town in Denbighshire, Wales, ten miles southwest of Wrexham. It's on A5, the historic stagecoach route, and close to the English border, so it's been a tourist destination for 200 years. It's notable for its abbey, the spectacular leaping aqueduct that carries the canal, and the fine half-timbered abode of the "Ladies of Llangollen".
