I divide my leisure time equally between the outdoors and indoors. I'm an occasional surfer, geocacher, and runner. A couple of years ago I joined British Military Fitness, which is boot camp style training delivered by ex-soldiers in a local park. It's very very hard, but enormous fun, and great for improving my fitness. I'll blog about that soon.
Indoors, I'm an incorrigible geek. I play and build computer game levels. I love all sorts of board games, and no puzzle is too hard to try. My record for the Rubik's cube is just under a minute. Yay me.
