Following the success of the Great Strides 65 Series, the Cystic Fibrosis Trust is pleased to introduce its first ever Ultra Marathon to the 2017 event calendar! The Great Strides 65 Ultra is a circular trail run passing through the Surrey Hills, a designated Area of Outstanding Beauty. It uses the well-established route for the “Great Strides 65” challenge event (a team sponsored walk). This event is being organised by and at the expense of the Cystic Fibrosis Trust to raise awareness of Cystic Fibrosis and badly needed funds to help in the battle against the UK’s most common inherited fatal disease. We ask runners to raise funds exclusively for the Trust.
