There's a boxing gym on Tower Bridge Road
near Tanner Street
, I don't know if it does kickboxing though.
Regarding running, the Greenwich Tritons triathlon club have weekly running sessions, I didn't actually get around to joining them last season but from the email correspondance I had with them, they seemed to be a friendly bunch.
Hope that's of some help!
