Yes it will end if you find the right people to talk to, and learn about how to stay healthy. Although ARTHUR LYDIARD is often misquoted, if you read a lot about what he said it will make sense to you.
There is a lot of emphasis on hard interval training!
Lots of coaches and athletes do not realize that you have to have a progressive periodization program. In short this means that you work on the Aerobic System all year long, with short sprints (100 yards or less) one day per week, for most of the year.
Be sure that you have enough time to recover completely from hard runs. Even long, slow runs can debilitate you if you are not getting recovery.
The AEROBIC SYSTEM determines your ultimate peak.
Clearly you do need to run hard intervals (10 x 200, 6 x 400, 4 x 1000, 3 x mile, etc.) but you do them in the right doses and at the right time.
10 weeks out from the first serious race of a season you start building up the hard interval sessions. Do this in a progressive fashion. Then with 4 weeks before the key race, you begin cutting down the intensity, and number of interval runs. (I would start out with ONE DAY of intervals, then after 3 weeks go to TWO days of intervals. (It does matter how hard you run and how many, that I cannot help you with from afar!)
Also most people race too much. It is not only important to limit the number of meets, but do not run more than one race per meet!
ARTHUR LYDIARD said that if you run too hard you run the risk of having too much acidity in the pH of your blood. This will cause injury, sickness, or staleness. We see top runners run in races when they are sick! Unless it is the league, or state championships that's pretty silly.
A program like the one I suggest is not common, neither is winning. One must do the things it takes to win. (Perhaps your problem is that you are simply not getting enough easy days. An easy day can be a 5 mile run, but it depends!) Read, and find good people to talk to about this. No book or what I just told you is complete!!!
