I am a member of North Brooklyn Runners, although I haven't made it out to a group run in a while, and it is a great group. If you live in Brooklyn you should see for yourself, and if you are the type that wants to investigate prior to commuting yourself, here is the link to their website: http://northbrooklynrunners.org/.
My guilty pleasure is Fútbol/Soccer, especially La Liga! Barça!!
