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

CGG 155 Mile Ultra is now a Badwater 135 Mile Ultra Preferred Qualifying Race!

The CGG 100/155 mile ultra will be retired after the 2024 race. This will be your last opportunity to run this epic race.

The CGG 155 came to fruition in 2015 by a group of Rough Runners from Savannah, Ga. We 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. The more the CGG is promoted, the greater the impact it will have on it coming to fruition. Every year in March, we hold a race to promote and help bring this dream to reality.
The CGG is comprised of 20% trails and 80% highways. Obviously, we would like the CGG to be all on trails, but currently, we have to deal with highway running mostly. Sadly, after ten years, the CGG still comprises 20% trails and 80% on highways.

What to expect:

Not to shy you away, but be aware that most of this run is on Hwy 17. You may encounter wildlife, stray dogs, and encounter unsafe drivers. It is imperative that you are able to stay alert throughout your journey. You will also encounter some of the most beautiful views that many don’t get the opportunity to take in. Everyone that ran this race seems to leave with quite a story, or life altering experience that you will carry for the rest of your years.

 Race Info:
