Lake Norman magazine's August 2009 issue has an article on the area's greenways, both current and in development. Not all greenways are dirt trails, nor are all greenways asphalt. For example, Lake Norman State Park has nearly 13 miles of trails suitable for running and mountain biking. Conversely, Davidson's Southeast Greenway of nearly six miles is a combination of asphalt with concrete sidewalk connectors. Also good for cycling and running.
Pick up your copy of this month's Lake Norman magazine at most any local shopping center.
