London 2 Brighton Trek Challenge

The London 2 Brighton challenge trek is a rewarding Capital-to-Coast trek taking place over the May Bank Holiday weekend, Saturday 23 and Sunday 24 May 2026, where around 2,000 adventurers walk, jog or run from Richmond-upon-Thames in London to Brighton on the south coast. The flagship option is a 100 km ultra-distance challenge that starts from the Thames, heading out over the North Downs and through the beautiful Surrey and Sussex countryside, before crossing the South Downs and finishing with the exhilarating sight of the Brighton coastline and the finish at Brighton Racecourse. Shorter distances such as 50 km, marathon, and 25 km options, make it accessible for a broad range of fitness levels. There's a challenge for everyone! 

By taking on a challenge event you'll help us support over 350 babies, children and young people who are seriously unwell – helping them, and their families, to make the most of every day.
