There are several couch-to-5k and running apps on the market that can help you accomplish your goals. I've tried several of them, but none have been as entertaining as Zombies, Run! created by Six To Start and Naomi Alderman. It's like listening to an audiobook about a zombie apocalypse, but you're the main character! This 5k training program will have you progress from walking to running three miles in eight weeks. The running and walking intervals are timed and woven into the story line. This app has storytelling, music, and mobs of zombies to get your heart racing and your feet moving.
