P90X is delayed Back strain this Morning

Options
I was so excited about starting the P90X today and early this morning I pulled or strained my back. I am taking it easy
but upset that this may effect my running. I have a 1/2 marathon that I am training for. This past Saturday, I ran 10.2 miles and felt
great. I hope this is something minor and I can come back and at least continue my running. I may have to wait on the P90X.
