Let’s get one thing straight: I firmly believe that running outside is superior to running inside, especially when running inside means running on a treadmill. Running outside on a track, a trail, or pavement is better in nearly all aspects, from maintaining form to reducing impact and stress on joints. But let’s get another thing straight: running at all is better than not running and there are some days when running outside just isn’t realistic for most people.
