Time to take on something lighter in the week. Make sure you are getting the necessary things that allow you to run at your normal, or elevated pace.
No matter how much you can endure during your routine. You need to rest and allow yourself to take a break.
The saying of all work and no play is never a good thing.
We all need to find balance in the course of our lives, so we prevent from breaking in the process. If you exclude rest from you work, you will eventually break and take even longer to reach your goals.
