Having accountability while training is a powerful motivator. Enter the Park Cities Morning Running Group. This rotating band of diehards meets at 6 am, Monday through Friday, at different locations around Dallas for runs into the Park Cities and beyond. The routes vary in distance, but count on at least a 5-miler. The group’s tireless leader, Bill Shipley, is always welcoming to new faces, and the only requirement for “membership” is an introduction.
