There will be an aerobic fitness crossover. Add swimming & you may seen a even greater crossover.

There are so many factors involved.
The definition of a
taxing routine, from one person to the next fitness fanatic, is apples & oranges. Its about knowledge, research, application & listening to your body. Your body will know when its been taxed, trying to stay within the realms of not under/over training.
Are you looking to get into triathlons?.
