Should I let chronic training load drop (as in stop training) to end my current level of tiredness or continue riding?
At the end of one particularly hard road racing season, I felt pretty tired as well. I decided to take about 3-4 days completely off the bike and by the end of that I felt good again and ready to go. If you haven't even taken that off you might try. Also be sure to eat right and get enough sleep if you're not.

But everyone's body is different. Attempting to build form back up "from the beginning" seems like a strong initial reaction if you haven't tried more simple R&amp;R first.
