1. Do not start any training plan until you have been cleared by your doctor to engage in rigorous physical activity.
2. These plans are an outline for your training. Every week should include one day off or one day of very light training.
3. Juggle the activities around your personal schedule, access to a pool and weather limitations.
4. Without knowing your individual goals and abilities it is impossible to give specific training times or effort. In general you want 2 swims, 2 bikes and 2 runs each week.
For the intermediate plan it would be 3x for each activity. One tempo, one interval and one long slow distance.
