By now, you have run a total of 39 miles. You will have had some good, some bad, and some in between days with running. This is normal. Follow the advice of your Yoga instructor: be aware of your bad days, but don't judge yourself too harshly. If you have not already done so, start a training journal. Record the details of your training and how you feel before, during, and after working out. Take photos as well. This journal will help you keep track of your schedule. It will also help you beat discouragement and boredom when they come.
