Six kilometres is the average distance a woman or child in the developing world walks for water. Too often, for water that causes illness or even death.
Join Team World Vision and go the distance to help children have clean water. From walking six kilometers to running a marathon, make every step count when you raise funds for World Vision water programs.
World Vision reaches one new person with clean water every 10 seconds! We can only do it with your help.
