COPENHAGEN â A 6-kilometer (3.7 miles) walk or run would tire anyone out. Thatâs the average distance people in developing countries have to walk every day to collect water that is often unsafe to drink. To raise money to help fund water projects, a local World Vision Global 6K for Water was held Saturday, starting at Copenhagen Central School. World Vision is a Christian humanitarian organizaton with a focus on helping children around the world, including the United States. These runs help fund its efforts of providing water to communities that lack easy access to clean water. Copenhagen has been hosting a 6K for five years.
