I'm using a pretty cool app to help me prepare for the running season. It is call Zombies, Run!. It is a game of running to collect supplies for your base that you can build up. And as you run it tells a story. At certain parts of your run, you start to hear zombies and you have to run faster for at least a minute or you lose supplies. Pretty interesting! If you want to follow along with my progress, the link is below. There is nothing on it as of right now, I just bought it
