If not, do something that makes sense. Adaptation needs to be specific to attain your goals. You must train duration specific energy transport systems and you must train pace specific neuro-muscular responses. Don't train any more than you have to Lazy runners are healthy runners. There are no bonus points for doing a harder workout than you'd planned.
Most injuries seem to occur when runners feel good and over do it.
Remember that how you feel is a poor physiological measure of how you are. Error on the side of conservatism. If you feel bad, do less. If you feel good, stick to your plan. Don't do more.
