J Running, Inc. produces high profile running (and walking) events, providing well planned races that focus on family, community and fun. What began as a vision for a Marin County Turkey Trot has evolved into a number of events, varying distances, spread throughout the year that attracts the competitive athlete to the casual walker. For over a decade, they have taken their favorite places to run in Marin County and turned them into incredible courses, whether it’s through the dirt trails of Marin’s open space to the two lane roads that meander through the quaint downtown of Marin’s unique cities.
