Running on a treadmill is great for your body but can get a bit boring after a while. The vxFitRunPi is a virtual training system that helps you get a more interactive running experience at home. It has a smart tracker with Bluetooth 5.3 connectivity. It comes with a running app that lets you run in virtual worlds.
You can use this tracker with your phone, Apple TV, tablets, and other devices. This project is getting funded on Kickstarter.
