Running on pavement can amplify the pounding on your joints  and cause injury. Hard surfaces can cause excessive stress to your ankles  and may make them hurt after running. Your knees are vulnerable, too, and running on pavement poses a significant risk of osteoarthritis later in life.
So choose soft surfaces such as grass or dirt – like you’d find in a park. Or run on a good quality treadmill, which will be low-impact and gentler on your joints. But avoid mushy surfaces such as sand or uneven surfaces. They can lead to twisted ankles and other injuries.
