The route description is good. If you get on an industrial area don't think your lost, you should be close Also there will be some maintenance on the roads so be carefull with speedlimits. Maybe good to know that the usage of ortman tires is highly recommended because of grib conditions and the fact that using any oil or whatever on sponge tires is not allowed.
