Does alcohol slow us down?

The days of Tour de France riders hydrating mid-race with wine, beer and champagne (Bicycling 2016) are long behind us and generally speaking, we all know that excessive alcohol consumption can harm our physical and mental wellbeing

That said, whether a social few after a busy week at work, a celebratory champagne or a glass with dinner to wind down, alcohol is incredibly present in our livesPlus, a crisp, cold beer can seem like a fitting reward to a hard and hot day in the saddle, pool or gym! 

So, what is the effect of drinking on our sporting performance? 

General Health

Firstly, keeping good health is key to being consistent in our training and racing (and most things in life!) Though several studies tout the health benefits of some wine and beers, the fact remains that most people are drinking far more than the recommended guidelinesResearch also suggests that alcohol consumption suppresses the immune system, making you vulnerable to illness – which in turn knocks out your training schedule and morale. 


It is widely accepted that your quality of sleep is compromised by alcohol. Sleep is the most important weapon in your recovery arsenal (and it’s free!) Essentially poor sleep equals poor recovery which impacts your ability to handle training load and increases your risk of injury and illness.  


Many people who sign up to an event do so to help maintain a healthy weight. And in turn, a healthy weight can aid positive performance. Given alcohol is relatively calorific, with few nutritional benefits, sticking to a low to moderate amount of alcohol will help you maintain a healthy size for your physique (NHS). Simple as that. 


Though some pros swear by one glass to aid with relaxation and pre-race nerves, the fact is there are few benefits to drinking alcohol when it comes to athletic performance. Common side effects reported by athletes include dehydration, heavy legs, fatigue, slow reaction times and a tangible loss of strength and endurance. Watch this 2018 GCN Show for more info. 

You can mitigate the effects of alcohol by eating something nutritious first, drinking water between drinks, limiting the amount you drink on a single occasion – two drinks is a good guideline – and taking at least two alcohol-free days a week.  

The GCN also make the interesting point that whilst alcohol has few benefits for general health and performance, cutting every pleasure out of your life for the sake of performance may inadvertently have a negative psychological effect. Essentially, pursuing moderation may be more beneficial to your performance than total abstinence, if that level of strictness makes you feel deprivedunhappy or more prone to binge.  

Looking to cut down? Some tips

All considered, lowering your alcohol consumption seems a no-brainer for anyone training for an athletic event in 2020. But this is easier said than done! As the almost 4 out of 5 Brits who admit they drink more than they want or intend to (Alcohol Change UK Dec 2019) will attest to. 

Here are some tips if you are looking to reimagine your relationship with alcohol: 

  • Book a race! For many people, having a race booked gives them the social excuse to reduce their alcohol consumption in the face of adult peer pressure. “Ah sorry mate, I would love to but I’m running a marathon on Sunday” has quickly become a well-tested ‘get out of jail free’ card for those looking to avoid the round of tequila! 
  • Focus on what you are gaining, not on what you are missing out on. Better sleep, no more hangovers and brighter skin to name a few. The most compelling reason? More money to spend on your tri gear...!  
  • For those who look forward to a cold, refreshing lager on the finish line, there are more and more low alcohol (2%) and alcohol-free beers making their way onto the market. Erdinger Alkoholfrei has B vitamins and is isotonic – making a great choice for those who want to enjoy a beer without compromising health and performance.
