Try biking. I can't run due to a hip issue and it has been very fun for me.

I love biking! And I do bike a lot. In fact, I often bike and run on the same day. But where I live, biking is only feasible about 5 months out of the year unless I invest in a bunch of cold weather gear. (And impossible at least 2 months out of the year due to snow/ice/slush/etc.)
