This is a great application. Very simple, clean interface with well-explained workouts. It really does exactly what is says and is great for beginner to intermediate triathletes. Some new features (not sure if these are allowed by apple) would be a link to the nike plus workouts for the runs, the ability to buy other workouts from the app (longer distances, more advanced training) and finally a desktop version to sync to and keep track of things.
