How many days should I load beetroot before a race?
3-6 days of consistent supplementation saturates the nitrate pool and raises baseline blood nitrite levels, amplifying the acute dose effect on race day. Three days is the minimum for measurable benefit; 5-6 days provides diminishing returns but near-maximal saturation. Do not load for more than 7 days continuously without a 1-2 day break.
The Dietary Nitrate Loading Protocol: Race Week Mastery
In the 72 hours leading up to a major competition, every nutritional decision counts. While most athletes focus on carbohydrate loading, elite performers focus on Nitrate Loading.
A single dose of beetroot before a race is beneficial, but clinical research (Jones et al., 2014) shows that a multi-day loading protocol results in significantly greater improvements in time-trial performance and oxygen economy.
This guide outlines the precise calendar for saturating your nitrate pool.
The 3-Day Race Week Calendar
To achieve the "Threshold Edge," you must saturate your system with inorganic nitrates for three days prior to your start gun.
Day 3 before Race (The Base Load)
- Morning: 1 serving of Beetroot Pro® Dark Cherry.
- Evening: 1 serving of Beetroot Pro® Dark Cherry.
- Goal: Begin building the nitrate pool in the blood and salivary glands.
Day 2 before Race (The Saturation Load)
- Morning: 1 serving of Beetroot Pro® Dark Cherry.
- Evening: 1 serving of Beetroot Pro® Dark Cherry.
- Goal: Achieve full systemic saturation. Maintain consistent levels to optimize mitochondrial response.
Day 1 before Race (The Maintenance Load)
- Morning: 1 serving of Beetroot Pro® Dark Cherry.
- Evening: 1 serving of Beetroot Pro® Dark Cherry.
- Goal: Ensure the body enters race day with maximal nitrate availability.
Race Day (The Tactical Deployment)
- Timing: 1-2 servings consumed 90 minutes before the start gun.
- Goal: Time the peak blood nitrite concentration (60 to 150 minutes post-ingestion) to coincide with your highest intensity effort.
Why Loading is Superior to Acute Dosing
While an acute (one-time) dose provides immediate vasodilation, chronic loading (3+ days) triggers secondary adaptations:
- Mitochondrial Remodeling: Chronic exposure to nitrate has been shown to improve the efficiency of mitochondrial respiration (Larsen et al., 2011).
- Tissue Saturation: Nitrates are stored in muscle tissue and can be released during periods of low oxygen (hypoxia), such as a final sprint or a heavy climb.
- Blood Pressure Stability: Multi-day loading provides a more stable reduction in systolic blood pressure, reducing cardiovascular strain during prolonged endurance events.
Protocol Checklist for Success
- Avoid Mouthwash: Do not use antibacterial mouthwash during the loading phase. Oral bacteria are required to reduce nitrate to nitrite. Mouthwash kills these bacteria and can completely block the performance benefits of beetroot.
- Hydration: Maintain high water intake to support blood volume and circulation.
- Consistency: Use a standardized extract like Beetroot Pro®. Raw juice or non-standardized powders are too variable to guarantee the 6 to 8 mmol dose required for this protocol.
The Bottom Line
Carb loading fills your fuel tank; Nitrate loading optimizes your engine's efficiency. By following the 3-day protocol, you ensure that every ounce of oxygen you consume is used with maximal efficiency.

How many days should I load beetroot before a race?
3-6 days of consistent supplementation saturates the nitrate pool and raises baseline blood nitrite levels, amplifying the acute dose effect on race day. Three days is the minimum for measurable benefit; 5-6 days provides diminishing returns but near-maximal saturation. Do not load for more than 7 days continuously without a 1-2 day break.
Should I take beetroot the morning of a race even after loading?
Yes. The loading plan builds a saturated nitrate baseline; the acute race-morning dose provides a final spike on top of that baseline. Take one serving 60 minutes before the start. Skipping the race-day dose after loading leaves performance on the table.
Can I load beetroot nitrate during training blocks?
Yes, and this is recommended for high-volume training periods. Daily supplementation during a training block may enhance adaptation by improving oxygen delivery during hard sessions, allowing higher quality work. Some athletes supplement every training day during a build phase and only use the 3-day taper protocol for target races.
