How to track user's speed and distance using GPS in Unity?

Hi guys,

So I have a running app that I want to make but I have never used the GPS API in Unity. I was wondering if Unity has some sort of built-in tool that allows me to track the users distance and speed when the user first starts running and when the user finishes running. If Unity does not have some sort of built-in tool interface for it is there something in the Unity asset store that I could use?
