Hi guys - reading the responses to that post got me thinking as I have only experienced this type of knee pain once or twice and it's only ever been on longer runs. I try to run on the grass berm alongside the pavement as I read that running on concrete pavements is bad for your joints, I'm wondering if the uneveness of the grass berm is what caused my knee pain now. What are your opinions on the lesser of these two evils 1) running on the hard pavement or 2) running on the grass berm which is uneven sometimes? Any feedback is appreciated. :p
