Julia and Nick are bravely taking on the London marathon representing Thames Water and raising money for our project in Madagascar.

All funds raised will go towards WaterAid's work to bring clean water, decent toilets and good hygiene to communities in Madagascar, in partnership with Thames Water.

We're supporting WaterAid because clean water, decent toilets and good hygiene are essential human rights and must be a normal part of everyone's daily lives. With your help, we can change normal for good - together.
