6 Kilometers is the average distance people in the developing world walk for water – water that is often contaminated with life-threatening diseases. On Saturday, May 22nd , thousands of people from around the globe will walk or run 6K to bring life-changing clean water to communities in need. Each participant’s $50 registration fee provides life-changing clean water for one person, so when you participate in the Global 6K you take that distance away from people in need. Register.
