Set in the picturesque surroundings of the Surrey Hills this 10k course will be a serious hill-climb challenge to the summits of Box Hill.

With steep gradients and a mixture of grass, woodland tracks and paved paths the route will mount challenging inclines but with the ultimate reward of unrivalled panoramic views across the surrounding countryside and towards the south coast.

Here are some of the key statistics of the terrain:


40% marked paths
30% grass
30% woodland trails

Before the race starts there will be a short warm up and safety briefing.
