As a self coached athlete I would love the ability to make my own custom training plan that I can modify and reuse. The work around right now is to create all the individual workouts in my library and add them individually to on my calendar. This is extremely labour intensive and requires me to keep separate documentation of the plans. Adding a training plan building feature for self coached athletes to the premium membership would really by value-added and make the whole experience of planning our training more efficient and enjoyabe.
