Cycling up or Down in Training

Cycles.I found an article in my research that is helping me tremendously to understand possibly why I had injuries this year.  Its about cycles, and the explaniation is pretty logical.  I went from doing 13 km in the winter for my longer runs- 15 km to 24 km.  This buildup with no real reprieve is immensely problematic to the need for our bodies to recuperate and rest.  True of life as well. We are not machines, impervious to wear and tear.  We are organic.  Resting is a part of growing, of strengthening and of producing.  Its as important as the actual work.  Swing to either side of the pendulum and there will be trouble. So I am realizing there is much more to learn about preparing for a race, about planning for improvement and for making gains in life.  To everything there is a season.
