Overtraining: It's Symptoms, Effects, and Solutions

Overtraining is one of the five most common training mistakes that a long distance runner can make.

The drive to excel, beat a time goal, become stronger, place first, can contribute to an athlete running too much and becoming "stale".

This condition can affect any type of athlete but endurance runners are more prone to suffer from it due to the nature (endurance level) that the sport requires. 

What is Overtraining?

The definition of overtraining varies from individual to individual because of different capability levels but it can be generalized by: 

Overtraining in Relation to an Endurance Runner: Performing runs that are too long and/or too strenuous for their level or experience with not enough rest periods to recover

It is normal to experience physiological fatigue that sets in after an intense workout or race. It usually takes no longer than 2 weeks for your body to get back to a well rested state.

The result is an increase in our motor performance (depending on what the workout targeted it will enhance our speed, strength, endurance, etc).

This is good for performance improvement and what we aim to do when we add such workouts as speed training to our routine.

However, it becomes bad when we fail to allow our bodies to rest when they are already in a state of fatigue and continue to push them into intense workouts.  If we continue to do this all the while postponing our much needed rest to beyond a 2 week period we begin to suffer from the effects of overtraining.

Other causes can be due to emotional factors such as our daily life anxieties, stresses and fears that can begin to creep into our training program. These will  end up making us feel burned out in the area of running.

Another common cause is feeling that all your hard work and training is not paying off.

Effects of Overtraining

There are 2 main effects of overtraining that can cause serious damage to a runner's career:

1. Sets the stage for an injury to occur and greatly reduces the ability of a runner's immune system to fight disease. The two most common injuries that an overtrained athlete experiences are stress fractures and tendinitis.

2. Results in a lack of enthusiasm for running and a feeling of being "burned out".   I'm pretty sure we all know what if feels like just to be "burned out" in even day-to-day life! 

Signs of Overtraining

Poor Performance

    Or a decrease in good performance. 

    As a runner we always want to try to put our best foot forward.  So when we are experiencing overtraining we might just feel like giving up.

    We might even start to feel discouraged because we are no long making the times in our runs that we used to be able to make.

Overtraining Poor Performance

Body Weight Loss

Body weight loss, which can be accompanied by a loss of appetite, and/or indigestion.

ALways Feeling Tired

You will feel tired from time to time especially after a long run, speed workout, or resistance training bout but you shouldn't be trying to just "get through the day" because you are so fatigued.

Overtraining Always Feeling Tired

Your Body Has a Hard Time Resisting Infections

You might find yourself with more colds, sinus infections, sore throats, even nausea and headaches because your body is being worn down.

Psychological Staleness

Or the feeling of being burned out. You might feel like you just can't run anymore and have no desire or enthusiasm to do so.

You have an elevated heart rate and blood pressure levels

When running and even at rest. If you haven't been keeping track of you heart rate it is a good time to start! Start here to find your target heart rate.

Insomnia or having a hard time sleeping

Whether it is falling asleep or staying asleep.  It can be rather miserable to suffer from insomnia.

How to Avoid Overtraining

It is fairly easy to avoid the negative effects of over training.

  • Plan appropriate regular rest days into your schedule

  • Reduce your training load when you find yourself feeling overly tired


Overtraining How to Avoid

The Solution: 

Cut down on your training volume and add rest days!

Take 3 to 5 days. Reduce your mileage for the week. Ignore your training schedule and get some rest. You may choose to keep your pace the same or just run easy.  Your body needs a break. Your mind needs a break.

Do not return to your regular training schedule until you feel rested, enthused and ready to continue. If you have big competition coming the best thing might be to pull out instead of pushing your body to an extreme.

Overtraining Solution

If you are a coach it is extremely important to watch out for this condition in your runners. Prevention is, as usual, the best way to avoid the negative effects. Keep in mind that  an overtrained runner needs your patience and empathy.

It will take a little bit of time but they should snap out of it in a timely manner as long as they are given what their body and mind needs.
