Ultra X Spring Trail Series

The Ultra X Spring Trail Series invites participants to explore the magnificent Serpent Trail—an undulating route that showcases the best of the South Downs National Park. Offering three distances—75km, 50km, and 25km—this event winds through greensand hills, winding rivers, ancient woodland, and rare lowland heath. Runners and walkers alike are welcome, making this a truly inclusive trail adventure. The race village serves as a lively hub with an expo, food and drink vendors, and a welcoming atmosphere that continues well after the finish line. With camping available on-site for the full weekend, it’s more than just a race—it’s a community celebration of nature and endurance.
