The ‘original’ Ultra Challenge! 2,000 or so adventurers will take on the Capital to Coast trails and test their grit & determination. Richmond-Upon-Thames is the start for most, 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 & hospitality all the way – and with half, quarter, Sussex Marathon & Brighton 25km loop options also available – there’s a classic bank holiday weekend challenge here for everyone!

Challenge Highlights

A lively start in Richmond – and then along the Thames to Kingston, and a picnic lunch near Sutton. On over the North Downs and through wonderful Surrey & Sussex countryside to the ‘half way’ point at Turners Hill. For full 100 km challengers – its more Sussex countryside and then up & over the steep South Downs with the Brighton coast then coming into view – followed by the final push towards a memorable Brighton Racecourse finish line.
