How to improve your gut health and how it can help with running


If you’ve ever tried a new food or supplement on race day, or you’ve found yourself pushing too hard, you may be familiar with runner’s gut.

An upset stomach certainly isn’t comfortable and can even take you out of a race altogether. New research shows that the gut can impact our running (and overall health) in other ways, too. 


Take care of your gut health by looking after the billions of helpful bacteria that reside there. The microbiome is the word that describes the environment that those bacteria live in – in our case, the entire gastrointestinal system. If you feed your body the wrong things, your gut can become imbalanced, and good bacteria may struggle to thrive. If you can look after your gut during off-season and your training months, it will pay off greatly on race day. Here are some foods to avoid and some to include for good gut health for runners. 


Reduce or remove these foods from your diet to improve your gut health: 


  • Alcohol 
  • Sugars
  • Artificial sweeteners 
  • Processed food 
  • Recreational drugs 
  • Stress and  
  • Caffeine. 


Some of those will irritate the gut, causing upsets that could have been avoided. You may be familiar with an acute stomach upset if you face anxiety before a race, for example. 


If you want to help reduce inflammation and encourage good bacteria growth, try these ideas. 


  • Add a probiotic to your diet. These help to top up the levels of good bacteria in your gut and can help address imbalances. You can usually find them in the pharmacy or the supermarket. 
  • Make your own probiotic drink such as kefir or kombucha. Commercially produced options are becoming more widely available. 
  • Manage your fibre intake well. Grab your fibre from natural sources where possible (fresh fruit and vegetables) rather than supplements. Don’t start supplementing fibre close to race day, as your gut may not accept a sudden increase gracefully. 
  • Experiment with fermented foods like sauerkraut and kimchi. The natural bacteria that ferments the vegetables can be great for gut health.  
  • Get plenty of monounsaturated fat into your diet from healthy sources like avocadoes, salmon and olive oil. These can help reduce inflammation in the gut. 


Good gut health can lead to better moods, better health and fewer upset stomachs during training and racing.

    What can I say, a wonderful invention. I have problems with my right foot in laced shoes so was a little dubious about trying the insoles. They are so comfortable to wear and give quite a lot of support. I would definitely recommend them. My mum also has a condition called foot drop and she has also got a pair and thinks they’re amazing, she now feels more confident about walking for longer periods as the insole gives her foot much need support.

    Plantar fasciitis pain
    Before trying these insoles I was unable to run more than a mile because of plantar pain. A couple of months later I completed a half marathon. They are also incredibly comfortable. I shall not run without these insoles again.

    Great insoles
    After experiencing plantar fasciitis in my right foot, I would try anything. These insoles are decreasing my pain and offer nice support. I would recommend these to friends and other runners!

    Great Insoles
    I bought the insoles during a 50% off sale to try it out. I just started running in them and had to get used to it the first few times. I feel like they give me an extra cushion during my landing. They squeak a little bit but I’m hoping that goes away after a few more runs.

    The real deal!
    I have been using these insole for just over a month and the difference they have made is incredible. I no longer have knee or ankle pain when running and feel much more stable. They took a little while to get used to but I cannot imagine running without them now. Amazing product.

    No more pain!
    These insoles have kept me injury free and have allowed me to be a faster runner. A year ago I had knee pain which kept me out of running for 6 weeks, my comeback was rough but since using these insoles I have had no issues. My feet never hurt and pain doesn’t radiate up to my knee. Couldn’t be happier with these insoles.

    5K Nailed!
    These Enertor insoles have proven really good for me. I ran my usual 5k circuit in them last night and it felt great. They’re really comfortable and deniitely seemed to make the run easier and more effortless. They slipped into my Nike trainers easily and are a really snug fit. They’re there to stay now!
