Half Marathon & 5K Run The Cause: We are excited to support "Go Red for Women" which is a movement began by the American Heart Association. A portion of the proceeds raised from this event will go to support this cause. Bunn Ranch is a 400-acre farm nestled just outside of Barnesville, GA in Lamar County. As a working cattle farm, it has been in use for the past 100 years. On the farm stands a 100-year-old farmhouse surrounded by land beautiful enough to provide a breathtaking backdrop wedding and other outdoor events If the open road and nature's beauty sounds welcoming then grab those running shoes and all your friends and mosey on down to the Bunn Ranch. We cannot wait to see you there!
