I live in Folsom, about a 30-40 minute northeast commute from Sacramento.

Here are links to some of the many cycling clubs in the Sacramento area:

I ride with CycleFolsom and love it (just started in May of this year).

I run by myself, so don't know what to tell you about running clubs . . . looks like Sacramento Fleet has some opportunities for you: http://www.fleetfeetsacramento.com/w...oup-walks-runs

Good luck on making your decision! We transfered here from AZ about two years ago and love it (although our bank accts. don't love it - housing is about 3x as much here . . . yikes!).
