Try soaring/gliding. My husband has been in love with it as long as I've known him, and since his club, like most German clubs, uses a winch (big old Oldsmobile engine) to launch the planes, each launch uses less than a liter of fuel. A skilled and lucky glider pilot can make that flight last for hours - my husband's personal best is something on the order of 8 hours and 800km. This sport requires a lot of help on the ground, so it's very social and physically active.
