Short rant.
I despise the term "training race".
You are either training or you are racing.
Calling something a "training race" is a built-in excuse for your performance, and develops a poor mindset: "I can go easy in a RACE".
If you enter a "B" race tired from a big training block, RACE IT, accept the result for what it is, and don't rationalize your performance.
Don't make excuses a bad habit that you bring to your "A" races.
As Wayne Dyer says... Excuses Begone!
