Running is good for your body and mood. Trying the same routes can get a boring after a while though. RunGen for iPhone is a handy app that creates new running routes for you to try. You simply have to select the distance you want to run and this app does the rest for you.
RunGen makes random routes around your location in areas you may not be familiar with. You can keep pressing the button to generate a route that you are more comfortable with. The pro version unlocks longer run distances and custom locations.[where to get it]
