In reply to biker bill: Decent depends.. try a few.. whats good for you is different to others, are you looking for a social scene.. racing.. improvements.. running partners.. structured training.. weekend trips.. road.. fell..
I like to be in a club with a chunk of runners better than me.. not overly so, but also have class runners around. But I also like active races.
Whats good for you maybe not so good for others, but don't feel compelled to join, just run with a club til you feel comfortable its for you.
