P-Biel/Grenchen/Plagne (31km)

Lovely route (all paved); till Grenchen is flat but it's ok to warm-up, then it starts really nice route and countryside. Most difficult part of the climb is probably 1km at 9% (around km 15, zone Kapelle Allerheiligen) then it's always mild climb around 5-7%, with wonderful view of the mountains and valleys. At Plagne (km 23) starts the downhill: it's quite straight with no turns and you have to control your speed. VERY IMPORTANT: just before km 27, while going downhill, you must turn left from main cantonal road to narrow street Römerstrasse, you need to be very careful. All in all, wonderful route in the area.
