Hi Ant,
There is loads of good cycling in the Basel area. Head off into the Jura if you want hills. The following is one of my favourite rides

There are a number of clubs in the area, I keep meaning to join one, but havent got around to it yet. The local club to me runs the Elsässerrundfahrt on May 3rd, a 130 km sportif type race, I plan to have a go this year.
