I'm swimming more than 2km of the most beautiful stretch of the River Thames in Henley at dawn to raise money for a wonderful charity. 

Starlight helps children to cope with serious illness by giving them tools to manage anxiety and isolation when they need it most. 

They use the power of play to create a sense of escape from the difficult reality in which these children find themselves and last they helped more than 1.2 million children in almost 500 hospitals across the UK.

They also support their siblings and parents by funding family breaks and away days, giving them a chance to make comforting, life lasting memories together, no matter what the future may bring. 

I've been swimming my whole life and it has always been a very important part of who I am, but this is the first time I take on a charity challenge and I couldn't be more excited. Please donate if you can!
