I'm aiming to swim the length of Coniston (5 1/4 miles) to raise money for Toilet Twinning. Toilet Twinning is helping to transform lives in some of the poorest places on the planet. Vulnerable households will: learn about the importance of sanitation and hygiene; build their own loo; gain access to clean water; enjoy better health - and take a massive step out of generational poverty.

Water and sanitation projects have a particularly positive impact on the lives of women and girls and research suggest that each pound invested in water, sanitation and hygiene projects could generate up to a £21 return through families having improved health and increased ability to work.

I really can't stress enough just how nervous I am about this. The furthest I have ever swum is 4 miles and that was in a heated pool with a nice black line on the bottom to keep me going the right way. I have been practising in open water but going in a straight line is still something of a challenge...My goal is just to finish without being timed out. I can't guarantee that I will finish but I promise that I will try my best!
