I'm Sick. Should I Run

I'm Sick. Should I Run?

As runners, we thrive on consistency. It's part of our identity to lace up and get moving, whether it’s a casual 5K or a marathon training session. But what happens when you wake up feeling under the weather? Should you push through or take a rest day?

Let’s break down when it’s safe to run and when it’s better to give your body the rest it needs.

The "Above the Neck" Rule

A general guideline for runners is the "above the neck" rule. If your symptoms are limited to things like a mild headache, stuffy nose, or a sore throat, it’s generally safe to head out for an easy run. In fact, light exercise can sometimes help clear congestion and boost your mood.

Best Practices:

  • Run at an easy pace: This is not the time for interval training or hill sprints. Keep the intensity low to avoid overloading your system.
  • Stay hydrated: Drink plenty of water before, during, and after your run, as your body may be more dehydrated when fighting off illness.
  • Monitor your symptoms: If you start feeling worse during the run, it’s a sign to stop and rest.

When to Rest

If your symptoms are "below the neck"—such as a cough, chest congestion, body aches, fever, or gastrointestinal issues—it's best to take a day off. Running with these symptoms can make your illness worse and extend your recovery time.

Reasons to Skip the Run:

  • Fever: Running with a fever can be dangerous. It puts extra stress on your heart and can lead to dehydration or heat-related illnesses.
  • Body aches: This is your body telling you it’s fighting something bigger. Give your muscles time to recover.
  • Chest congestion or a cough: These symptoms can make breathing difficult, and pushing through a workout could lead to more serious respiratory problems.

The Mental Battle

Taking a rest day can feel like a step back, especially if you're in the middle of marathon training. But remember, recovery is just as important as the miles you log. Skipping a run when you’re sick isn’t a sign of weakness—it’s smart training.

At Run The Day Apparel, we believe in listening to your body and knowing when to push and when to pause. Health comes first. You can always come back stronger after a day (or two) of rest. So, if you’re sick, trust the process. Take a deep breath, hydrate, and give your body the care it needs.

When You Can Return

Once your symptoms subside, ease back into your running routine. Don’t expect to pick up right where you left off. Start with a short, easy run and gradually increase your intensity and distance. The goal is to let your body fully recover without jumping back in too quickly.

Remember: showing up for your health, in the long run, means knowing when to take it easy. You’re not just running today—you’re building strength for tomorrow.


At Run The Day Apparel, we’re here to support you every step of the way. Whether you’re running through a perfect streak or navigating the bumps in the road, keep showing up for yourself, one step at a time.
