From the Promoter:
The 4G is the southernmost un-southern gravel ride and the uttermost unique ride of its kind in South Florida. The route covers the Gator’s share (or should we say Python’s share these days?) of remote areas you can find in the Miami-Dade area, featuring canals and access roads with very little pavement involved. We strongly recommend running nothing more narrow than a 40mm tire as some of the paths along the route can be quite demanding.
