The usual route is 18 miles with 1000 ft of elevation. You can easily skip some hills, by choosing the 14 mile ride. This route has a nice flow, and the surface is pretty clean. If wet surfaces are expected, it’ll cancel, as there are some sections of downhill. Usually there is a faster paced group 17-20 MPH . Often a slower group of 15-17 MPH goes also but that is not guaranteed as it depends on who shows up.
