Join Us for RunThrough Trails South Downs on Sunday 1st August 2027, in support of Brain Research UK!

Experience one of the UK's most iconic trail running destinations at RunThrough Trails South Downs on Sunday 1st August 2027. Starting from Queen Elizabeth Country Park, you'll take on a spectacular route through the rolling hills, ancient woodland and open chalk downland of the South Downs National Park.

Choose your challenge from 12K, 25K or 50K, with each route showcasing some of the region's finest trails, including sections of the famous South Downs Way. Whether you're stepping into trail running for the first time or preparing for your next ultra-distance adventure, there's a distance to suit every level of runner.

Expect grassy tracks, woodland paths and rewarding climbs that open up to sweeping views across Hampshire and Sussex. Enjoy fast-flowing descents, beautiful countryside and a true escape into nature before returning to the welcoming event village.

With clear waymarking, well-stocked aid stations, supportive marshals and the friendly atmosphere you've come to expect from RunThrough Trails, you'll have everything you need for an unforgettable day on the trails.

Whether you're chasing a new challenge, building confidence on technical terrain or simply looking to explore one of England's most beautiful national parks, RunThrough Trails South Downs promises an incredible trail running experience from start to finish.

All routes will be marked using trail flags and tags, along with A5 arrows and signage. Our friendly marshals will also be on hand to guide you at major junctions and cheer you all the way to the finish. However, please note with all trail races, routes can be disrupted by many things: the weather, disgruntled walkers and wildlife, to name a few! To keep you safe, we provide the GPX for your race route so you can check you’re on track throughout the race and course correct/self-navigate if necessary.

With RunThrough, you can expect a lively event village and clear guidance from our on-course team. After your run, enjoy food, drink and free finish-line goodies from our partners.

You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.

Once you enter, you’ll receive a confirmation email straight away, and full event information will be sent to you closer to race day.

We look forward to seeing you on the start line.
