London 2 Brighton Ultra Challenge May 2026

The original Ultra Challenge is now in its 11th year. Walk, run or jog mostly off-road from the start in Richmond and on towards the North Downs, through wonderful Surrey and Sussex countryside to Turners Hill at halfway (with optional camping). The full 100 km challenge then heads up and over the South Downs before the welcome sight of the Brighton coastline and the racecourse finish line. There are distance options to suit all!
