In addition to what Pasheteh Yid said, don’t skimp on the shoes,gedt the best ones that your budget will allow. In terms of support and sjock absorption, your knees and joints will thank you.
In terms of where you run, I agree that parks and roads in the country are more inresting, but are harder ( concrete and asphalt ) are hard on the knees. Boardwalks ( in the winter when there are no bathers walking around ) with their wood surface and ocean views are great.
