What to expect

The North Downs 50 is a serious endurance challenge, taking you across rolling hills, woodland trails and open countryside. It will ask a lot of you, in training and on the day, and the sense of achievement at the finish is worth every mile. Take it on for Momentum and every tough mile will help us be there for families of seriously ill children and those navigating bereavement.
