One thing not to do when you suffer from hurting knees is cycling in a landscape with many hills. I learned that the hard way, last week. The boys wanted to go out cycling with me and it was too hard to say no to them. So we went cycling and I must say, it was a lot of fun. My husband had just replaced his bicycle tyre, so he went along as well. The boys were excited and they wanted the 'long route'. We cycled for quite some time, hills up and hills down and when we came home we all took a well-deserved ice cream. It was a great day and I do not regret it at all!
