Back by popular demand, the North Downs Ultra Challenge is returning 50km route which takes in some of the best of the Surrey hills, the North Downs Way, and the surrounding countryside.

Setting out from the Guilford basecamp you’ll walk, jog or run through Chantry Woods overlooking the scenic Chilworth and Chinthurst Hill, with breath-taking views to be experienced at the top of St Martha’s Hill – also home to a historic church!

With some ups and downs along the way, you’re guaranteed to experience some of the best views over Surrey Hills, especially when roaming through the renowned nature reserve of Newlands Corner.
