London to Brighton Ultra Challenge

The ‘original’ Ultra Challenge! 2,000 or so adventurers will take on the Capital to Coast trails and test their grit & determination. A Richmond-Upon-Thames start, and it’s over the North Downs with wonderful Surrey & Sussex countryside to halfway at Turners Hill. The full 100km route heads over the South Downs before the welcome sight of the Brighton coastline comes in to view. You’ll get full support all the way – and with half, quarter, Sussex Marathon & Brighton 25km options also available – there’s a challenge here for everyone!

Push yourself further in 2027 and take on an Ultra Challenge, the UK’s No.1 Series of treks and trail challenges.
