This is part 4 of a 80 km long ride in the beautiful Val-de-Fier area in eastern France (a bit west of Annecy). I don't think there is a single flat km in this 80 km. Lots of short climbs and descents. Great for training and excellent to get to know this hilly area. Try to do the 4 parts on one day, or in one week. Enjoy!!
