The ‘original Ultra Challenge’ – and once again over 2,000 adventurers will take on the Capital to Coast route and test their grit & determination over the weekend.

Richmond-Upon-Thames is the start, and it’s over the North Downs with wonderful Surrey & Sussex countryside to half way at Turners Hill.

The full 100 km 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 three quarter, half, marathon & quarter distance options also available – there’s a classic challenge here for everyone!
