“Mountain climbs, beautiful river views, and a gravel KOM” is the way this route was promoted when put on as a Gran Fondo in 2019. Even though the route then was mostly paved road, it appears the difficulty of the gravel was undersold. The event has not been put on as a Gran Fondo since.
However, with a gravel bike sporting 40 mm tires and a few route modifications (which we made!), we think this route has potential. We recommend you give it a go in the spring when the dirt / gravel is firm, the washboard is less, and the days are not brutally hot.
Note, we recentlyupdated (January 2021) the route to remove a significant stretch of highway riding. This changed the start location and the distance / elevation gain. Also, the route may now ride better in the opposite direction from that we have mapped.
We have not ridden this route, thus the Development Route designation. However, we would appreciate your feedback if you give it a go. Leave us a comment below.
