Grace and Alice are attempting to swim 6km down the River Avon - that's 6,000m, or 200 lengths of a pool and 5km further than either of us have swam before.

We are doing this challenge not just to have bragging rights on every holiday swim from here on it, but to raise money for Level Water, a charity using the power of swimming to vastly improve the life of children with disabilities- everyone should be able to enjoy the water like we do!

Just £15 can change a life. Please support us in this epic challenge by making a donation and we promise we will stop mentioning it soon x
