5K to 10K is the perfect app for those looking to take their running to the next level. Developed by Active Network LLC, this free app is designed for individuals who have completed the Couch to 5K plan or are already 5K-ready. With motivating virtual coaches and a 9-week training program, you'll be prepared to run a 10K (6.2-mile) race in no time.

The app requires just 25 to 70 minutes, three times a week, for nine weeks to get you 10K-ready. The selected virtual coach, whether it's Constance, Billie, or Sergeant Block, will guide and support you throughout your workouts. Real-human audio cues will keep you on track and motivated.

One of the standout features of 5K to 10K is the ability to listen to your favorite playlists with the in-app music player. You can also calculate your distance and pace, as well as map your routes using the free GPS support feature (requires iPhone 4 or later and iOS 7.0 or greater).

Challenge yourself with progressively faster paces as you log your workouts and share your progress on Facebook. Stay motivated and achieve your running goals with 5K to 10K.
