There isn't a one-size-fits-all answer here as beginner runners will likely be looking for assistance with a little bit of everything like performance tracking, help in discovering local routes, and training.
But, everyone has to start somewhere and we know just how valuable it is to get to grips with the different kinds of runs you can do that will help you progress quicker and learn more about the beauty of the sport. In this area, we highly recommend the Runna app for beginners.
It thrives in breaking down running lingo and shows you how you can get better at running and do so without getting injured. Although this is a running app you have to pay for, the knowledge it equips you with during a training block should leave you feeling confident enough to end your membership and apply what you've learned to your independent training.
