welcome to the forum.
Some enthusiastic chaps often organise some sort of road trip on this site, on the other hand you could always catch up with the Baden triathlon club
, or the mountain bike club
Every Sunday the mountain bike club meet up at the Gemeindehaus Obersiggenthal at 09:30, but contact them first so that they know to wait for you. Most speak English, though there are a lot of Engineers in that lot, from memory...
