It depends, what is your body telling you? I'm a big believer of listening to your body and not whatever cookie-cutter/template information is out there. If you feel sluggish/drained, have trouble sleeping, feel depressed, lose your appetite, or find yourself feeling ill you may be over training.
The most important thing when training at a pace like this is consistent, restful sleep and a clean diet with plenty of calories. If you aren't training you should either be sleeping or eating. Listen to your body. As a side note, taking a week or so off from training may yield some decent gains in strength and endurance.
