Skydiving, juggling, hobbyist hacking (R-Pi, home automation, etc), iRacing (and online racing sim) and Civilization 5. Both skydiving and juggling fulfill my enjoyment of teaching my body to do complex things and both reward me with easily being able to "get in the zone". Both relax me greatly too. My little tech projects are very enjoyable while I'm working on them and very rewarding when I put something together that me and my family use every day. The online multiplayer driving sim is similar in that it has a ridiculously long learning curve (which attracts me about so many things I've done in my life). It also fills my need for competition. For the last 20 years, since I was 16, I've used competitive gaming as an outlet for my competitive streak. Beginning with FPS games (the Quake series in particular) and then Starcraft 2 and now iRacing. I treat Civ 5 like modern chess and use it to fill hours of spare time.
