How to stay hydrated during ultra marathon?

Ultra marathon running is a grueling test of endurance, requiring physical and mental stamina to conquer long distances often lasting over 6 hours. One crucial aspect of performance and overall well-being during these demanding races is proper hydration. In this blog post, we'll explore effective hydration strategies for ultra marathon runners to help them stay strong and safe throughout their epic journeys.

Consistent Fluid Intake

To maintain hydration levels during an ultra marathon, it's essential for runners to consume fluids regularly. Aim to drink approximately 150-300ml (5-10 oz) of fluid every 15-20 minutes to replenish sweat losses and support optimal performance. Setting a schedule for fluid intake can help runners stay on track and prevent dehydration.

Stay Ahead of Thirst

Waiting until you feel thirsty to drink may not be sufficient during an ultra marathon. Thirst is not always a reliable indicator of hydration status, especially during intense exercise. Instead, make a conscious effort to stay ahead of thirst by hydrating at regular intervals, even if you don't feel thirsty.

Monitor Individual Needs

Hydration requirements can vary among runners based on factors such as sweat rate, environmental conditions, and personal tolerance to fluids. Pay attention to your body's cues and adjust your fluid intake based on how you feel, as well as the specific demands of the race.

Electrolyte Balance

In addition to water, maintaining electrolyte balance is crucial for optimal performance in ultra marathons. Sweating over long periods can lead to significant losses of sodium, potassium, and other electrolytes. Consider incorporating electrolyte-rich drinks or supplements to support hydration and prevent cramping.

Practice During Training

It's essential for ultra marathon runners to practice their hydration strategies during training runs to fine-tune their approach. Experiment with different fluids, intake schedules, and electrolyte sources to determine what works best for you and your body.

Impact of Weather Conditions

Weather can significantly affect a runner’s hydration needs. Hot weather increases sweat rates, leading to higher fluid and electrolyte loss. In such conditions, you might need to increase your fluid intake and consider wearing loose, breathable clothing and using cooling strategies like wet sponges or ice packs. Conversely, in cold weather, the feeling of thirst may be diminished and you might not drink as much as necessary. Additionally, cold air can increase respiratory water loss. Thus, it's crucial to stay vigilant about your hydration status even if you don't feel thirsty in cold weather. Plan your hydration strategy based on weather forecasts and adjust to the conditions on race day.

Impact of Humidity

High humidity levels also significantly impact hydration needs and can exacerbate the risk of dehydration and heat-related illnesses. Recently, several accidents have occurred in Hong Kong where hikers suffered from dehydration and excessive heat despite having water. The high humidity impairs the body's ability to cool itself through evaporation of sweat, making it harder to regulate body temperature. In such environments, it's even more critical to monitor fluid and electrolyte intake closely.

Inclusion of Electrolytes: Simply drinking water is often not sufficient to replenish the complex mix of nutrients lost through sweat, especially in challenging conditions. A balanced hydration strategy should include sufficient electrolytes such as those found in natural sports supplement like Endu1's Honey Boost Dual Fuel endurance hydration. These products help to restore sodium, potassium, and other essential electrolytes, which are crucial for maintaining performance and preventing cramps and other hydration-related issues.

By following these hydration strategies, ultra marathon runners can set themselves up for success on race day and mitigate the risk of dehydration or overhydration. Remember, staying hydrated is key to performing at your best and enjoying the incredible challenge of an ultra marathon. Good luck and stay strong out there on the trails!
