The description of the trainingplan groups can you find here. This description is also displayed when you select a group.
Every plan can be adjusted down in length and intensity level. A standard reduction level is considered seven (7) seconds per mile while running and five (5) seconds per 100 meters swimming.
You can specify a special discipline (swimming, cycling, running) for your training plan. In this case, you will receive an additional optional training unit in your plan. These can be completed or exchanged for another.
