Spotting the signs of over-training and intervening early can help you to avoid months off the bike and save your ultra event.
The first step to over-training is often under-recovery. Even if you feel good it’s worth regularly checking your training to check that you are having regular easy periods. You can use the 'form' metric in TrainingPeaks or Strava and ensure it is allowed to rise to around 0 at least once per month. If use another method, just be sure to have a very easy week - it doesn't have to be complicated with numbers if you don't like them.
If you catch things early, before they drift too far, an easy week or a few days off and a cautious return can be enough to get things back on track.
More rest is required the worse things get and if you are in a state of Chronic Overtraining it can take, weeks, months or even years to get back to normal.
So be careful and if you think you may be getting into trouble, err on the side of caution and consider talking to someone who is experienced in helping athletes. A bit of help now may avoid a lot of unhappy suffering.
