P-Biel/Grenchenberg/Romont (54 km)
Wonderful route (all paved); till Grenchen is flat but it's ok to warm-up. First climb (Grenchenberg) is 13.5km at 6.8%, about 8-10% first half, then almost flat. Take care downhill because pavement is not very good. Second climb starts with 1km at 9% (zone Kapelle Allerheiligen) then it's always mild climb around 5-7%. VERY IMPORTANT: just after km 50, 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.
