While not essential for the basic 5K training plan, if you're interested in taking your running further these might be enough to tempt you to upgrade. There's also a Pro version (opens in new tab) available, which includes extra feature such as calorie counting and distance tracking.

This not only give you access to additional apps, but opens up more training programs including 10K, half marathon and full marathon. The free version of the app has a ceiling of 5K, but if you like the idea of taking things further, you can buy a Zen Unlimited Pass as an in-app purchase. You just need to commit 30 minutes a day and the program should work.

The training program incorporates walking as well as running to help you build stamina and gradually work towards hitting your ultimate goal. With just three workouts per week, you should be able to tackle a 5K within eight weeks. The secret of the app's success is that it is gentle, but not too gentle. This is an Apple Watch running app with a very specific goal in mind: getting first-timers (or anyone who's returning to running after a long break) up to speed and able to keep going for five kilometers.
