The app allows you to create training plans of up to 16 weeks, viewing your workouts one week or one day at a time. It also saves the plan to your phone, so you can access it even if you don't have 3G or WiFi access. You can also email and print your training plan and receive discounts and offers from Runner's World on running gear and other items of interest. There's also a free version of the app with most of the functionality of the paid version. And, since the app is brand-new, you can get it for just $1 for a limited time.
