Beetroot For Runners: Can It Really Improve Your Running Performance?

Most runners are constantly looking for ways to improve their performance. Some invest in the latest running shoes, others focus on training plans or recovery techniques, and many experiment with sports nutrition products. One natural performance aid that has received a huge amount of attention in recent years is beetroot. Once known simply as a colourful vegetable found in salads and sandwiches, beetroot has become one of the most researched foods in endurance sport. Elite athletes, marathon runners and cyclists regularly consume beetroot juice or concentrated beetroot shots before races and hard training sessions. The reason is simple. Beetroot contains high levels of naturally occurring nitrates that may help improve blood flow, increase endurance and allow runners to perform at a higher level for longer. But how much of the hype is supported by science, and is beetroot really worth adding to your training routine?

What Is Beetroot?

Beetroot is the edible root of the beet plant, known scientifically as Beta vulgaris. While most people recognise the familiar deep red variety, beetroot also comes in golden, white and striped forms. The entire plant is edible, including the leaves and stems, although it is the swollen root that is most commonly consumed. Beetroot has been part of the human diet for thousands of years and was originally developed from wild sea beet, a plant that grows naturally along coastlines throughout Europe, North Africa and parts of Asia. Today, beetroot is grown worldwide and is valued not only for its distinctive flavour but also for its impressive nutritional profile.

A Brief History Of Beetroot

Beetroot has a surprisingly rich history. Ancient Greeks and Romans cultivated beet plants for both food and medicinal purposes. While the leaves were often eaten as vegetables, the roots were used to treat a variety of ailments. Historical records suggest beetroot was used to help with digestive complaints, skin conditions and even wound healing. The Romans were particularly fond of beetroot and considered it something of a luxury food. Fast forward to the modern era and beetroot has become a staple crop across Europe, with large quantities grown in the fertile soils of regions such as the Cambridgeshire Fens. What was once valued primarily as a food source is now attracting attention from sports scientists around the world because of its potential benefits for endurance athletes.

Why Are Runners Interested In Beetroot?

The answer lies in one word: nitrates. Beetroot is naturally rich in dietary nitrates, which are compounds that the body converts into nitric oxide. This process begins in the mouth, where naturally occurring bacteria help transform nitrates into nitrites before they are converted into nitric oxide within the body. Nitric oxide plays a crucial role in widening blood vessels and improving circulation. For runners, this matters because improved blood flow means more oxygen and nutrients can be delivered to working muscles. Better oxygen delivery can improve endurance, reduce the effort required to maintain a given pace and potentially enhance overall running performance.

How Does Beetroot Improve Running Performance?

The biggest benefit of beetroot appears to be its ability to improve exercise efficiency. Research has shown that nitrate-rich beetroot can reduce the amount of oxygen required during exercise. In simple terms, your body may be able to perform the same amount of work while using slightly less energy. For runners, that could mean maintaining a pace more comfortably, delaying the onset of fatigue or having more energy available during the closing stages of a race. Studies involving endurance athletes have found improvements in time trial performance, running economy and overall exercise tolerance following beetroot supplementation. While the gains won't transform an average runner into an elite athlete overnight, even a small improvement can make a meaningful difference when chasing a personal best.

Beetroot And Endurance Running

The further you run, the more important efficient oxygen delivery becomes. During a marathon, half marathon or long training run, your muscles are constantly demanding oxygen to sustain performance. As fatigue builds, any factor that improves oxygen utilisation may help maintain pace and delay exhaustion. This is why beetroot has become particularly popular among endurance athletes. Some studies have reported performance improvements of around two to five per cent during endurance exercise following beetroot supplementation. That may not sound like much, but over the course of a marathon it could potentially translate into several minutes. For runners chasing time goals, those are gains worth paying attention to.

Can Beetroot Help You Run Faster?

This is the question most runners really want answered. The evidence suggests that beetroot may help some runners run faster, particularly during endurance events lasting longer than thirty minutes. The benefits appear to be most noticeable among recreational and club runners rather than highly trained elite athletes, although research remains ongoing. One reason is that elite athletes may already have highly efficient cardiovascular systems, leaving less room for improvement. For most runners, however, the possibility of improving endurance, reducing fatigue and increasing exercise efficiency through something as simple as beetroot is understandably appealing.

Other Health Benefits Of Beetroot

While running performance tends to dominate the headlines, beetroot offers a number of additional health benefits. Because nitric oxide helps relax blood vessels, regular beetroot consumption has been associated with lower blood pressure and improved cardiovascular health. Some research also suggests that increased blood flow may benefit brain function by improving circulation to areas responsible for movement, coordination and cognition. Emerging studies have even linked beetroot consumption to improvements in oral health by supporting beneficial bacteria involved in nitric oxide production. While runners may be attracted by the performance benefits, the wider health advantages make beetroot a valuable addition to almost any diet.

What Is The Best Way To Take Beetroot?

The good news is that you don't have to drink large quantities of beetroot juice every day to experience potential benefits. Whole beetroot, beetroot juice and concentrated beetroot shots can all provide useful amounts of dietary nitrate. Many runners prefer concentrated beetroot shots because they deliver a consistent dose without requiring large volumes of liquid. These products are often blended with apple, lemon or other fruit concentrates to improve the taste. Whole beetroot remains an excellent option too and can easily be added to salads, smoothies, sandwiches or roasted vegetable dishes. From a nutritional perspective, both approaches can be effective.

When Should Runners Take Beetroot?

Timing matters if you're hoping to maximise the performance benefits. Most research suggests that nitrate levels peak approximately two to three hours after consumption. As a result, many runners take beetroot juice or a concentrated beetroot shot around two hours before a race or key training session. Some athletes also follow a loading protocol, consuming beetroot daily for several days before an important event. While the exact strategy varies between individuals, most studies agree that the benefits are greatest when nitrate levels are elevated before exercise begins.

Are There Any Downsides?

Beetroot is generally considered very safe and is well tolerated by most people. One side effect that occasionally surprises runners is beeturia, where urine or stools take on a pink or reddish colour after consumption. While it can look alarming if you're not expecting it, it is completely harmless. Some people may also experience mild digestive discomfort if they consume large quantities of beetroot juice in a short period of time. As with any nutritional strategy, it's important to test beetroot during training rather than trying it for the first time on race day.

Is Beetroot Worth Trying?

Few foods have attracted as much attention from sports scientists as beetroot and unlike many sports nutrition trends, there is a substantial body of evidence supporting its potential benefits. The nitrates found naturally in beetroot appear to improve blood flow, enhance oxygen delivery and increase exercise efficiency, all of which are highly relevant to endurance runners. While the improvements are unlikely to be dramatic, they may be enough to help you maintain your pace for longer, delay fatigue and potentially achieve a faster race time. Combined with its wider health benefits and relatively low cost, beetroot is one of the simplest and most accessible performance aids available to runners today.

Final Thoughts

Beetroot won't replace consistent training, sensible pacing or a well-structured nutrition plan. There are no shortcuts when it comes to improving as a runner. However, when combined with good training habits, beetroot may provide a small but meaningful performance advantage. Whether you choose whole beetroot, juice or concentrated beetroot shots, it's an option that is backed by considerably more science than many of the supplements marketed to runners. If you're looking for a natural way to support your endurance, it's certainly worth giving beetroot a try before your next big race.
