Coastal Georgia Greenway 100 and 155 Mile Ultra (CGG 155, CGG 100)

The CGG 155 came to fruition in 2015 by a group of friends from Savannah, Ga that were fascinated by the aspect of an envisioned long corridor of trails and green space spanning the coast of Georgia from St. Mary’s to Savannah, Ga. The visionary for the Coastal Georgia Greenway is Ms. Jo Claire Hickson. She’s worked hard for the past twenty years trying to bring to fruition her vision of the CGG. Our way of helping her realize her dream and vision is to host an annual long run the last weekend of March called the CGG 155. The more the CGG is promoted the greater the impact it will have on it coming to fruition.

The CGG is comprised of 20% trails and 80% on highways. Obviously, we would like the CGG to be all on trails but currently, we have to deal with highway running mostly.

The CGG 155 starts Friday, March 5th at 5:00 am on Hutchinson Island, Savannah, Ga., in between the Savannah Convention Center and, the Westin Hotel.
