Triathlon With a Cold: Should You Train and Race When You’re Sick?

should you train or race triathlon with a cold or flu

Are you feeling under the weather but worried about losing your hard-earned triathlon fitness if you skip training? You’re not alone. Many triathletes grapple with the question: Should you continue training when you have a cold? In this article, we’ll delve into the research, explore signs indicating whether it’s okay to train or take a break, and discuss the risks and potential benefits of training while unwell. We’ll also look at how you can track your recovery to make informed decisions about training when sick.

Understanding the Research on Training with a Cold

Based on various studies, the general consensus is that if your symptoms are mild and above the neck—such as a runny nose or sore throat—it may be acceptable to engage in light exercise. However, if symptoms are below the neck, like chest congestion or body aches, it’s usually best to give your body the rest it needs.

It’s important to note that these recommendations are general and may not apply to everyone. Factors such as the severity of your cold, your overall health, and the type of workout can influence your decision. If you have symptoms like a fever or generalized body aches, it’s advisable to rest and recover before resuming training.

Research has also indicated that moderate aerobic exercise can improve the progression and well-being of patients with illnesses. However, “moderate” means that you’re never out of breath or exercising for extended periods.

Moreover, regular exercise is generally good for your immune system. Triathlon training can strengthen your body’s ability to fight viruses. However, immediately after tough workouts or races, your immune system can become temporarily weakened.

Should You Train With a Cold?

When coaching athletes, I often advise them not to train until their symptoms have almost completely subsided. This is partly because, when you’re feeling under the weather, you may not enjoy training or feel motivated to exercise—perhaps your body’s way of telling you to rest. Additionally, you might not gain significant fitness benefits from training while battling a virus. Training is a form of stress that breaks your body down so it can recover and build back stronger. If you’re fighting a virus, your body’s resources are already taxed.

“Listen to your body. If you’re feeling unwell, rest might be the best medicine.”

Risks of Training with a Cold

Training with a cold comes with risks, including the potential for myocarditis, an inflammation of the heart muscle often caused by viral infections. This serious condition can significantly affect your heart’s function and overall health. Another risk is prolonging or worsening your illness by over-stressing your body when it’s already fighting a virus.

Detraining and Taking Time Off

Worried about losing your hard-earned fitness gains? The effects of detraining typically start after 7 to 10 days of inactivity. Taking a few days off doesn’t have to set you back. In fact, a short break can sometimes lead to greater strides in the long run. However, prolonged breaks can lead to a decline in fitness, and unfortunately, the older you are, the quicker you may lose fitness.

When to Rest and When to Train

There are clear signs indicating that you should rest, such as a significant decrease in performance, persistent fatigue, or an elevated heart rate during exercise. There are also ways to track your body’s readiness:

  • Monitor Your Resting Heart Rate: An elevated resting heart rate can be a sign that your body is under stress. Marathon world record holder Paula Radcliffe used to monitor her resting heart rate each morning and would skip training if it was outside her normal range.
  • Heart Rate Variability (HRV): HRV is a useful metric that can provide insights into your physiological state. A high HRV indicates a healthy heart and a strong capacity to handle stress, while a low HRV can suggest that your body is under stress from illness or intense exercise. Many modern fitness watches and apps can track HRV.

Conclusion

When you’re feeling ill, it’s often better to play it safe and rest. Light exercise during mild symptoms may not be harmful, but it’s crucial to listen to your body. Tools like HRV monitoring can provide additional insights into when it’s appropriate to resume training.

Always consult with a healthcare professional if you’re unsure about training while sick.

Takeaways

  • Listen to Your Body: Rest when you’re experiencing significant symptoms.
  • Monitor Your Health: Use tools like resting heart rate and HRV to make informed decisions.
  • Consult Professionals: When in doubt, seek advice from medical professionals.

Planning Your Off-Season

You can start our Off-Season (Fitness Maintenance) plans anytime you like.

They’re designed to help you maintain a good level of fitness when you’re not specifically targeting an event, such as, during the off-season, or anytime you’re taking a break from racing.

Planning For Your Event

For the best outcome, input the date for your “A” target race and the tool will default to a plan that will fill that gap nicely. If you want, you can then adjust the plan length to start it on a different day.

Note that you can still work in other, smaller races during your plan too!

The longer plans start easier and progress more gradually. This has a bearing on the difficulty level you choose. For example, a 12-week plan starts off at a higher level than a 36-week plan because with 12 weeks left there’s not as much opportunity to build up slowly.
