Crucial In-Race Top-Up Strategy for Long-Distance Events

20 oct. 2025

Why In-Race Nitrates Are recommended for endurance events

When tackling a long-distance race—whether it's a marathon, an ultra-run, a centuries-long bike ride, or an Ironman—your body is a highly complex machine under extreme duress. You diligently train your cardiovascular system, your muscles, and your mental fortitude. You practice your fueling. But there’s one performance factor that often gets overlooked: the need for a mid-race nitrate top-up.

You’ve likely already incorporated Stamox beetroot powder into your pre-race routine. By taking it in the 1-3 days leading up to your event, you’ve effectively loaded your system with dietary nitrates. These nitrates convert into nitric oxide (NO) in your body, a powerful molecule that plays a vital role in vasodilation—widening your blood vessels. This allows for more efficient blood flow, which means your working muscles get more oxygen and nutrients with less effort. In essence, it helps lower the oxygen cost of exercise, allowing you to maintain a higher pace for longer.

But here is the crucial point for any long-duration effort: The benefits of that initial nitrate loading are not infinite.

The Science Behind the Decline

Your body is constantly metabolizing and utilizing the compounds you ingest. Research into the effects of dietary nitrate on exercise performance suggests that the beneficial plasma nitrite levels—the immediate precursor to nitric oxide—can naturally begin to decline during prolonged, intense exercise. This happens as your body continues to use the available NO to support blood flow and muscle function.

If you hit hour three or four of your race without topping up, you are likely missing an opportunity to sustain those "peak" performance benefits you felt at the start. As those plasma nitrite levels drop, the efficiency of your oxygen delivery begins to decrease, and your perceived effort to maintain a certain pace starts to climb. This is when the dreaded "bonk" or simply a noticeable slowing of pace can begin to set in.

This is why an in-race top-up is crucial—it's a proactive strategy to sustain the physiological edge that Stamox gives you.

Your Crucial Stamox In-Race Top-Up Strategy

Implementing a mid-race nitrate top-up is simple and can be a game-changer for maintaining a consistent, strong pace deep into your event.

1. The Strategic Timing: Every 2-3 Hours

Unlike your initial pre-race loading, the in-race top-up is about maintenance, not saturation. The goal is to consistently replenish the declining plasma nitrite levels.

Strategy: Consider topping up your nitrate levels every 2 to 3 hours during your race. For a six-hour race, this would mean two top-ups. For a ten-hour endurance event, you might aim for three to four. This regular interval helps smooth out the physiological dips and keeps your nitric oxide production consistent.

2. The Optimal Dosage: The Maintenance Measure

You don’t need the full pre-loading dose for a top-up. A smaller, more manageable dose is effective for sustaining the benefit and is easier on your digestive system mid-race.

Dosage: A smaller dose of Stamox beetroot powder, around 1 tablespoon (approximately 10 grams), is the perfect amount for this maintenance strategy. This quantity provides a significant nitrate boost without the volume of liquid or calories that might complicate your primary fueling plan.

3. The Practicality Principle: Portability is Key

Long races demand simplicity and practicality. Fumbling with packets or mixing drinks can cost you time and focus. Therefore, ease of consumption is paramount.

Practicality: The most effective way to manage your Stamox beetroot powder top-up is to pre-mix it into a highly portable liquid solution.

  • Mix it into a race bottle: Blend the 10g serving directly into one of your smaller water, electrolyte, or carbohydrate mix bottles. Label it clearly as your "Stamox Top-Up" bottle.
  • Use a soft flask: For runners, mix the dose with a minimal amount of water or sports drink and carry it in a small, accessible soft flask or pocket.
  • Consume with food: If you're using a liquid-based carbohydrate fuel (like a thick gel or liquid shot), you can even mix the Stamox into a small flask of this for a combined nutrient and NO boost.

By mixing the Stamox beetroot powder into a drink, you ensure quick, fuss-free consumption, allowing you to focus on the task at hand: maintaining that hard-earned pace.

Keep the Pace High and Effort Low

Your Stamox beetroot powder is more than just a pre-race boost; it’s a tactical tool that is crucial for long races. By committing to an in-race top-up, you’re making a deliberate choice to fight back against the natural physiological decline that plagues endurance athletes. Sustain your plasma nitrite levels, maintain efficient oxygen delivery, and keep your perceived effort low, allowing you to finish strong and hit your target pace. Don't just start strong—stay strong.
