MTB folklore tells a tale of an epic 100-mile bike race that ran at Kielder many years ago. Notorious for breaking bikes and breaking wills this was a stunning test of machine and body in the wilderness of the Northumbrian borderlands. The route consists of a single 31-mile lap that strings together all the best bits of Kielder. Yes, you guessed it, twice round for 100km and three times round for the 100 mile. This route makes use of the superb purpose-built trails. The route promises to be fun whilst the distance turns it into a huge challenge.
