Hydration: Beyond "Drink, Drink, Drink"
Tailoring Your Fluid Intake for Peak Performance
We've all heard the mantra: replace every drop of sweat. But is that really the key to peak performance? At TrailMed, we're here to debunk the outdated "100% replacement" myth and help you discover your personalised hydration strategy.
Remember those 80s/90s sports drink ads pushing gallons of fluid? While well-intentioned, they contributed to a surge in hyponatremia cases, a dangerous condition caused by overhydration. Imagine, up to 10% of Ironman Frankfurt finishers experiencing hyponatremia – that's a significant performance and health risk!
The Truth About Dehydration
The reality is, most athletes can tolerate a degree of dehydration without sacrificing performance. Striving for 100% replacement can be counterproductive. We've seen athletes complete ultra-distance events with measurable weight loss, rarely exceeding 10%. The ideal range? For most, it's likely between 2-4% bodyweight loss.
Individual Hydration Needs: Jess's Desert Ultra Journey
Like no two trails are the same, no two athletes have identical hydration needs. That's why we're excited to share Jess's recent experience. Preparing for a grueling desert ultra marathon, Jess underwent our Personalised Hydration Plan. This consultation provided concrete data about her individual sodium loss. It helped to guide her through how to better understand her sweat rate during training and likely sweat rate in the desert, which is crucial for developing a personalised hydration plan.
Why Sodium Matters
Sodium plays a vital role in fluid retention. A 2015 Spanish study during a hot half-Ironman revealed that athletes supplementing with sodium lost less bodyweight and outperformed those on a placebo by an average of 26 minutes! This highlights the clear link between proper sodium intake and improved performance.
Cramp Prevention: The Sodium Solution
Are your cramps kicking in during intense sweat sessions, hot weather, or late in long activities? Do you follow a low-sodium or low-carb diet? Then, upping your sodium intake could be a game-changer.
Here's the kicker: many sports drinks fall short. Standard options often contain 200-550mg of sodium per 32oz (946ml), while athletes can lose around 950mg! TrailMed recommends targeting 1,000mg+ sodium per 32oz (946ml), especially if you're a "salty sweater."
Practical Sodium Tips:
Electrolyte Drinks: Look for drinks with 1,000-1,500mg sodium per liter.
Food/Capsules: Aim for a similar ratio: 1,000-1,500mg sodium per 32oz (946ml) water.
Table Salt: Table salt (NaCl) is only 39% sodium. So, ~3g of salt provides ~1,170mg sodium.
Our friends at Precision Hydration found that 89% of athletes who had cramping issues found supplementing with sodium helped them manage or eliminate those cramps. That's a strong endorsement.

General Hydration Principles:
Pre-Hydration: Start hydrating well before your activity.
During Activity: Sip fluids regularly, and consider electrolyte drinks for prolonged or high-intensity exercise.
Post-Hydration: Replenish lost fluids and electrolytes.
-
Short runs (under 1 hour): Water is usually sufficient.
Long runs (over 1 hour): Carry water or an electrolyte drink.
Hot weather: Increase fluid intake and consider electrolyte supplements.
-
Use water bottles or hydration packs.
Electrolyte drinks are essential for long rides, especially in warm weather.
-
Hydrate before and after swimming.
For long swims, consider taking breaks to drink fluids.
-
Carry sufficient water, especially for long hikes or hikes in hot climates.
Consider a hydration pack.
Electrolyte drinks and salty snacks can help replace lost minerals.
Changing What You Drink:
Water: Ideal for shorter, less intense activities.
Electrolyte drinks: Replenish lost sodium and other minerals.
Sports drinks: Provide carbohydrates for energy, as well as electrolytes.
Consider Food: many fruits and vegetables contain high water content, and can assist with hydration.
Key Considerations:
Sweat rate: Individual sweat rates vary greatly.
Weather conditions: Hot and humid weather increases sweat loss.
Exercise intensity and duration: Longer and more intense activities require more fluids.
Stop guessing and start performing!
