London 2 Brighton Challenge

25-100km from capital to coast. Take on the challenge to help people experiencing homelessness.

About the event

The original Ultra Challenge returns — the iconic Capital to Coast route. Starting in Richmond-upon-Thames, the journey winds through the scenic North Downs and the beautiful Surrey and Sussex countryside, reaching the halfway point at Turners Hill.

From there, the full 100km route continues over the rolling South Downs, before the welcome sight of Brighton’s coastline signals the final stretch. With full support and hospitality throughout, and a range of distance options — including three-quarter, half, marathon, and quarter — there’s a challenge for everyone.

Walk, jog or run for St Mungo’s and help us to end homelessness for good.
