Cycling Route P-Biel/Sonceboz/St-Imier/CHASSERAL/Nods/Twannberg (73 km)

Wonderful route to climb le Chasseral from north, all paved. Nearly 25 km to warm-up (probably it goes up at 1%) then starts long climb to Chasseral, it's around 14km average 6%, but there are couple of downhills, so real climb is around 7-8%. Very nice wide road, take care of cars and motorbikes at weekends. Then fast downhill and, at km 59, it starts other lovely climb to Twannberg, that is more up and down with narrow tracks (no cars and all paved). All in all, lovely route.
