I play pickup soccer on saturdays and run away from my problems on a regular basis, usually about 3-5 km depending on how I'm feeling. I used to cycle a lot when I first got here but one of the Italians I rode with fell and really hurt himself so we basically stopped and I haven't done it more than a few times since.
I also have this weird habit of coming back home smashed and just doing hundreds of pushups. It's great, I don't feel it at all during the moment and then the next day I feel like John McCain.
A lot of people I know fast. Really helps you get your money's worth at the pub.
