The 7-Phase Race Protocol

Base PhaseDays 8 to 14 before race

1 serving Beetroot Pro® (morning)

Establish baseline nitrate saturation during normal training. Continue Endurance360® if using.

Loading PhaseDays 4 to 7 before race

2 servings daily (morning and evening)

Double dose begins saturating muscle tissue nitrate pools. Reduce intensity, increase carbohydrate intake.

Saturation Day 1Day 3 before race

2 servings daily (morning and evening)

Research shows 3 days at double dose is sufficient to saturate the nitrate pool for most athletes.

Saturation Day 2Day 2 before race

2 servings daily (morning and evening)

Rest or easy shake-out only. Prioritize sleep and hydration. Avoid antibacterial mouthwash.

Saturation Day 3Day 1 before race

2 servings daily (morning and evening)

Final loading day. Eat normally. No alcohol. Confirm race-morning timing plan.

Acute DoseRace morning

1 to 2 servings, 60 to 90 minutes before start

Skip antibacterial mouthwash. Brush only. Peak plasma nitrite aligns with race start at this timing window.

Recovery PhasePost-race recovery

1 serving within 60 minutes of finish

Betalain antioxidants in beet extract reduce oxidative stress and DOMS. Resume normal training dose the following day.

The Three Rules That Most Athletes Miss

Skip antibacterial mouthwash on race morning

The oral bacteria in your saliva convert dietary nitrate to nitrite, the precursor to nitric oxide. Antibacterial mouthwash (chlorhexidine, cetylpyridinium chloride) kills these bacteria for hours. If you rinse at 6:30 AM and take your supplement at 7:00 AM for an 8:00 AM start, you may operate at 30 to 60 percent of the expected nitric oxide effect.

Full explanation

Match your timing to your product format

Refined betaine nitrate extract (like Beetroot Pro): take 60 to 90 minutes before the start. Raw beet juice shots: take 2 to 3 hours before the start. Using raw-juice timing for a refined extract means the peak has passed before the gun goes off.

Protocol FAQ

Verify your dose is at the clinical threshold

The performance research is based on 300 to 600 mg of dietary nitrate per dose. Most commercial beet supplements contain 5 to 100 mg per serving. If your label does not list a specific milligram amount of nitrate, you cannot verify the dose.

Protocol FAQ

How many days should I load beetroot before a race?+
Three days is sufficient to saturate the nitrate pool for most athletes. Studies showing benefit from 5 to 7 day loading protocols used longer durations for statistical power in the study design, not because longer loading produces meaningfully more performance benefit. The practical protocol: two servings daily (morning and evening) for 3 days before the event, then the acute single serving 60 to 90 minutes before your start.
What time should I take Beetroot Pro on race morning?+
Take Beetroot Pro 60 to 90 minutes before your race start. This timing aligns with peak plasma nitrite for a refined betaine nitrate extract. Raw beet juice shots need 2 to 3 hours because the absorption pathway is slower. Using raw-juice timing for an extract means the nitric oxide peak has already passed before your start.
Can I take beetroot supplement every day during training?+
Yes. Daily use at one serving builds baseline nitrate saturation that compounds with the pre-race loading protocol. There is no tolerance or adaptation effect with dietary nitrate, so daily use remains effective throughout a training block.
Does mouthwash affect my beetroot supplement?+
Yes. The nitrate-to-nitric-oxide conversion requires oral bacteria in your saliva. Antibacterial mouthwash (chlorhexidine, cetylpyridinium chloride, alcohol-based rinses) suppresses these bacteria for 1 to 5 hours. Skip antibacterial mouthwash on race morning. Brush normally with fluoride toothpaste and do not rinse with any antibacterial product.
Should I take Beetroot Pro with or without food?+
Either works. Taking it in a fasted state (before breakfast) may produce slightly faster absorption but the difference is small at the clinical dose range. Most athletes take their morning loading dose with breakfast for convenience and to avoid any mild GI sensitivity on an empty stomach.
What should I avoid during the loading protocol?+
Avoid antibacterial mouthwash at any point during the loading window. Avoid proton pump inhibitors (omeprazole, pantoprazole) in the 48 hours before race day, as they reduce stomach acid and impair the nitrite-to-nitric-oxide conversion step. Alcohol and high-fat meals in the 24 hours before race start can blunt the vasodilation response.
