Why athletes love raw beets before workouts
Athletes love raw beets because they are a natural source of dietary nitrates that convert into nitric oxide, which improves blood flow, oxygen delivery to muscles, and exercise efficiency-key factors that can make a workout feel easier and a race finish faster. This "natural pre-workout" effect has been documented in multiple endurance and strength studies over the past fifteen years. As a result, many endurance athletes now include beet-based foods or juices in their training days and competition routines.
The science behind beet power
Raw beets contain high levels of inorganic nitrates, which the body converts into nitric oxide via a stepwise pathway involving salivary bacteria and nitrite reduction. Nitric oxide relaxes blood vessels, improving vasodilation and lowering blood pressure, which in turn allows more oxygen and nutrients to reach working muscles during a run, cycle, or swim. Because of this, exercise performance under beet supplementation often looks markedly better in time-to-exhaustion and submaximal-effort tests.
A 2025 meta-analysis of 17 clinical trials found that acute beetroot juice (delivered 2-3 hours before exercise) significantly boosted muscular strength (standardized mean difference ≈0.08) and improved lactate tolerance and time-to-exhaustion in healthy adults, especially when nitrate doses fell between 515-1,017 mg per serving. In trained athletes, the same analysis showed that chronic supplementation (≥3 days) also modestly increased VO₂max and delayed fatigue, though the effect sizes were small. These data suggest that raw beets or beet juice are not "magic bullets," but they do provide measurable, repeatable advantages for many competitive athletes.
Key benefits athletes pursue
- Improved endurance performance, especially in events lasting 8-30 minutes at high intensity, where nitrate-induced oxygen efficiency can lower perceived exertion and delay fatigue.
- Enhanced blood flow and muscle oxygenation, which may help athletes maintain higher speeds or power outputs late in races, such as the final kilometers of a 5K or a time trial.
- Reduced muscle soreness and faster recovery, partly due to the antioxidant profile of beets (including betalains and polyphenols) that combat exercise-induced oxidative stress.
- Better blood pressure and vascular health over time, which supports long-term training capacity and cardiovascular resilience in endurance athletes.
- A natural, low-sugar alternative to many commercial pre-workout formulas, appealing to athletes who want to avoid synthetic stimulants or proprietary "energy blends."
How much and when to eat raw beets?
Most sports-nutrition guidelines recommend consuming enough beet-derived nitrates to deliver roughly 350-600 mg of inorganic nitrate before competition, which often corresponds to about 150-300 g of raw beets or 250-500 mL of beet juice. Because the nitrate-to-nitric-oxide conversion takes time, organizations such as the Australian Institute of Sport suggest taking beet products 2-3 hours before exercise for optimal blood nitrate levels.
For a structured approach, many professional athletes follow a simple protocol: daily beet intake for 3-7 days before a key event, plus an acute dose 2-3 hours pre-race. This "double-phase" strategy aims to build a baseline nitrate reserve while also maximizing the acute spike when it matters most. Individual tolerance varies, so athletes are often advised to trial beet-based foods during training first to avoid digestive discomfort or beeturia (red-tinged urine), which is harmless but can be alarming.
- Three days before race day: add 100-150 g of grated raw beets to salads or smoothies at lunch or dinner to prime the nitrate pool.
- One day before race day: repeat the same beet serving, pairing it with easily digestible carbohydrates (e.g., rice, oats, or bananas) to fuel glycogen stores.
- Two hours before the race: consume an additional 150-200 g of raw beets or 250-300 mL of beet juice, ideally with a small, low-fiber snack to avoid gut upset.
- Immediately after the race: include beets in a recovery meal to support antioxidant replenishment and circulation during cool-down.
Raw beets versus other nitrate sources
Beets are not the only nitrate-rich food used by athletes; others include leafy greens like arugula, spinach, and lettuce, which can also raise nitric oxide. However, raw beets are often preferred because they pack a relatively high nitrate punch per gram and are easier to dose precisely than loose greens. For this reason, many sports nutritionists recommend beets as a "first-line" nitrate source for athletes who want measurable, repeatable benefits without over-complicating their diet.
Practical nutrient table for athletes
Below is an illustrative table showing approximate nutrient values for a typical raw beet serving relevant to athletes. Values are simplified for educational clarity, but align with standard nutrition databases.
| Serving example | Raw beets (100 g) | Beet juice (100 mL) | Impact on athletes |
|---|---|---|---|
| Calories | ~43 kcal | ~35-45 kcal | Low-energy, high-nutrient density supports sustained training without excess calories. |
| Dietary nitrates | ~100-150 mg NO₃⁻ | ~200-300 mg NO₃⁻ | Contributes to nitric oxide synthesis and improved oxygen efficiency. |
| Fiber | ~2.5-3.0 g | ~0.1-0.5 g | Supports gut health and satiety; higher in raw beets, lower in juice. |
| Potassium | ~300-350 mg | ~150-200 mg | Helps maintain electrolyte balance and blood pressure during hard training. |
| Antioxidants (betalains, etc.) | Moderate-high | Moderate | May reduce oxidative stress and post-exercise soreness. |
Common myths and caveats
One myth is that raw beets "instantly" make everyone run faster; in reality, response varies widely based on fitness level, nitrate intake, and gut microbiome. Some elite runners have reported that long-term beet use offers little extra benefit once they are already highly trained, which is why many resumed training without beet products after early enthusiasm. For this reason, experts stress that beets should be viewed as a small, evidence-based advantage rather than a guaranteed performance upgrade.
Other practical caveats include potential gastrointestinal discomfort from high-fiber raw beets, especially close to a race, and the cosmetic side effect of beeturia (red-colored urine or stool), which is harmless but can worry unprepared athletes. Dental professionals also caution that beet juice is acidic and may erode enamel over time, so rinse-with-water or dilution is often recommended.
How to add raw beets into an athlete's diet
Many endurance runners simply grate raw beets into salads, grain bowls, or wraps, pairing them with ginger, lemon, or apple to cut the earthy flavor and aid digestion. Others blend raw beets into smoothies with banana, berries, and Greek yogurt to create a quick, nutrient-dense pre-bed or post-workout drink. For those who dislike the texture of raw beets, lightly roasting or steaming them can soften the fibers while still preserving most nitrates, though this may slightly reduce nitrate yield compared with raw or juice.
Why athletes love raw beets: the final takeaway
Athletes love raw beets because they deliver high-density nutrition, potent nitrates, and a subtle but measurable edge in endurance, efficiency, and recovery. When timed correctly-usually 2-3 hours before exercise and built up over several days-raw beet intake can make a hard workout feel slightly easier or a race finish slightly faster without relying on synthetic stimulants. For well-informed athletes, raw beets are not a miracle, but a smart, evidence-backed piece of the performance puzzle.
Helpful tips and tricks for Why Athletes Love Raw Beets The Performance Edge Debate
How raw beets affect oxygen efficiency?
Raw beets increase nitric oxide, which makes the body use oxygen more efficiently during steady-state exercise. This means that for a given workload-such as running at a set pace or cycling at a fixed wattage-an athlete can maintain effort with slightly lower oxygen consumption, effectively stretching their endurance. Because of this effect, researchers often describe beetroot supplementation as a way to "lower the cost" of moving, which can be decisive in time-trial or race-like conditions.
Are raw beets better than beet juice?
Raw beets and beet juice both deliver nitrates, but juice concentrates them into a smaller fluid volume, making dosing easier for athletes who need precise nitrate intake on competition day. Raw beets add more fiber and chewing resistance, which some plant-based athletes prefer as part of a whole-food approach. However, juice can be more practical when athletes want a quick pre-race spike without a heavy stomach load, while raw beets may be better suited for daily dietary inclusion.
Which sports benefit most?
Beets show the clearest benefits in events where sustained aerobic effort and oxygen delivery matter most. Examples include long-distance running, cycling time trials, triathlon, rowing, and cross-country skiing, where small improvements in efficiency and lactate management can translate into meaningful time gains. However, some research also suggests that beet supplementation can modestly heighten power output and perceived exertion thresholds in team-sport and high-intensity interval training (HIIT) contexts.
What's a sample beet-based pre-workout plan?
Here's a sample plan an endurance athlete might use before a 10K race:
Are raw beets good for HIIT and strength work?
While most classic beet studies focus on endurance, newer research shows that beet supplementation can also modestly improve repeated-sprint ability and lactate tolerance in team-sport and HIIT contexts. In strength athletes, beet juice has been shown to slightly increase muscular strength and work capacity, though the gains are small and may be more noticeable in non-elite populations. For high-intensity athletes, beets may be most useful as part of a broader strategy that already includes quality training, sleep, and nutrition, rather than as a standalone performance fix.
Can beets interfere with blood pressure medication?
Because beets lower blood pressure via nitric oxide and vasodilation, they can theoretically interact with antihypertensive drugs, especially in people already on strong medication regimens. Athletes with diagnosed hypertension or cardiovascular disease are advised to consult a sports physician or cardiologist before using beet juice or concentrated beet supplements regularly. For most healthy, recreationally active people, however, moderate beet intake is considered safe and even beneficial for long-term heart health.
What does a sports dietitian usually recommend?
Sports dietitians often recommend treating beets as a "supplemental whole food" rather than a mandatory superfood. Leading practitioners suggest starting with modest daily portions (around 100-150 g of raw beets) for 1-2 weeks, then stacking an acute pre-race dose once the athlete confirms tolerance. They also emphasize that beets work best when embedded in a broader periodized nutrition plan that includes appropriate carbohydrates, protein, hydration, and recovery strategies.
