Walk the Thames Path for Shelter and every step will help end the housing emergency.
You can walk, jog or run and choose a distance that suits you. From a 10km loop to a 50km hike or a 100km ultra marathon, there's a challenge for everyone.
Starting at Putney Bridge in west London, the route follows footpaths along the River Thames. Passing through Richmond and Hampton Court, you'll trek to the halfway point at Runnymede.
For those who want to push their endurance, the full 100km route continues through Windsor and along the riverside. Finally, you'll finish like a champion in the picturesque town of Henley.
Get sponsored, raise vital funds for Shelter and be part of the fight for home.
