Yes.

Put the bicycle away for the next week.

Just walk ... casual, smell-the-roses type walks.

Ideally, you should plan your year so you hit this level of overtraining in about October (in Canada). Mid-October, I usually had cycled so much I was more than happy to walk away from the bicycle for a couple weeks, and it was OK because there were no events and the weather was really lousy. Then in November, I would get on the trainer ... and break out the cross-country skies.
