Colloquially, "concrete" and "cement" are often used interchangeably.

However, "cement" -- aka, Portland cement -- is actually just the binder in concrete -- which is a mixture of sand, gravel and cement; after water is mixed in, it is put in forms, where it hardens to become sidewalks, highways and -- unfortunately -- running tracks.

So I was running on both concrete and cement?
