Hi nicnac,

I can't help with Zug, but here's a few suggestions for Basel...

In Basel there is the Hash House Harriers (branches found worldwide): http://basel.harrier.eu.org/
I did a run or two with them a while back, very social and friendly, including beer stops en route !

Or if you're looking for something a little more serious, this club is also in Basel: http://www.lauftreff.ch (unfortunately only in German), but has some useful links on the site too.

There's a club that trains in Muttenz (just outside Basel). I'm afraid I'm not very helpful here, as I don't know what they're called or much about them as I only went along once with a colleague, but they meet and train Wednesday night at the track in Muttenz and along the Birs (river), and there were a few english speakers too! (sorry for complete vagueness!.. If it's interesting for you I will try to find out more.)

This site offers lots of info on running Switzerland (also not in english):

I hope that offers you some pointers!
