> my knees don't allow for it Start slow, buy shoes appropriate for your gait, work on technique. I have bad knees running in the family, had tendon injuries in both of them as a kid too. Used to get a lot of pain when running then I decided to focus on my technique, taking it slow (like, 2 mile runs at 10min/mile cause running longer or faster felt like the death) Now 3 years later I run a 4hr marathon and the only time my knees hurt is when it's time to buy new shoes. And yes, it is a great excuse if you don't actually want to run. My advice is for if you want to but think you can't :) PS: start slow can mean "long leisurely walk" depending on your shape. Tendons and joints need to get used to being used
