Great ride, but this is mainly a road route.
Nice ride lots of up and down on mainly packed gravel surface. Not sure if I would stop and do any drinking on the way if you want to stay safe, but that is your call. If you want to make this a harder ride do it in reverse their are more uphills this way.
