Beat Box Hill 50K Ultra Marathon

Beat Box Hill 50K Ultra Marathon

Think the South East is flat? Think again. The Beat Box Hill 50k is here to test your legs on some of the most iconic and punchy trails in the home counties.

Part of the RunThrough Trails 'Summit Series', this race takes you to the heart of the Surrey Hills Area of Outstanding Natural Beauty. Famous among cyclists for the Zig Zag road, Box Hill offers trail runners something even better: steep chalk paths, ancient woodlands, and some of the best viewpoints in Southern England.

Course

This is a route that demands respect. Covering 50km (31 miles), the course winds its way around the National Trust estate of Box Hill and sections of the famous North Downs Way.

Expect a proper mix of terrain underfoot. You’ll be running on hard-packed chalk trails, weaving through rooty woodland singletrack, and tackling plenty of steps (Box Hill is famous for them!). The route is designed to be "fast trails" for the fit runner, but with enough elevation gain to make it a genuine ultra challenge.

You’ll be rewarded for your climbing efforts with the stunning vista from the Salomons Memorial viewpoint, looking out over the Weald towards the South Downs. It’s a loop that packs a lot of variety into a relatively small area, making it intense but incredibly accessible.

If you are looking for a fully marked 50k ultra that feels wild but is easily accessible from London, this is the one. RunThrough events are renowned for their supportive atmosphere, meaning you get fantastic aid stations, enthusiastic marshals, and a buzzing event village. It’s a great stepping stone for runners looking to tackle their first hilly 50k, or for seasoned veterans wanting to blast their quads on the North Downs.
