Sussex Downs Trail Run

Join the Sussex Downs Half Marathon and run 9Km or 22Km for Amaze!

The Sussex Downs Half Marathon has a lot to offer. Whether it’s picturesque and unspoilt views you’re after or a challenging climb, there’s something for everyone.

There are two routes to choose from: 22Km Half Marathon route and a 9Km Standard route.

From here you will run a visually rewarding loop on sturdy trails towards Brighton before heading back up to the South Downs Way which will overload your senses with its amazing scenery.

You will then descend from the Sussex Downs hilltop enjoying the vast and sprawling views before a flat final 3 km to the finish.

Regardless of experience or ability, we actively encourage new runners to our events and have 2 route distances to choose from.

At the finish line you will receive a well-deserved high-quality metal medal, finisher’s gift and refreshing drink!
