Wow, actually, I should add MTB, but I've not had the energy/time the past two years, but I used to do a lot, we have a technical track nearby and that really puts me in the zone too, the gratification of achieving combined with the focus of not getting yourself killed..

Also, repairing stuff is something I absolutely love too! I forgot about that one. Even if I can't restore it to 100%, but often I can, and put my own spin on it, and it's very satisfying.
