Instruction: What is the best surface to run on?

Response: Running is a great exercise, but not all running surfaces are created equal. Traditionally, those who run "runners" will run 5-7 days a week. Runners will average between 3 miles per run up to 20 miles per run. While running is great exercise and very efficient at burning calories, it can be hard on the body. Specifically the leg joints. The average runner will strike the surface they are running on 1,480 times per mile. So if you are running 10 miles, thats just under 15,000 foot strikes. This repetitive striking can deteriorate the body joints over time. Therefore, the type of surface a runner runs on, can have a huge impact on the body. Some surfaces are harder than others, the harder the surface, the harder on the body, legs and joints. Concrete is harder than asphalt, asphalt is harder than a dirt trail and a dirt trail is harder than a high school track surface. Example, concrete can be 30% harder surface than asphalt. Running is a great exercise and millions of people enjoy running. But if you want to run long, as in for a long time, choose your running surface for the long run. Because the surface you choose to run on, can have a direct correlation to how long your body and leg joints will last.
