Should Runners Drink Water or Sports Drinks?
Water is best for short runs. Sports drinks provide benefits for runs over 60 minutes.
For most recreational runners doing runs under 60 minutes, plain water is perfectly adequate for hydration. Sports drinks become beneficial for runs lasting longer than 60-90 minutes, during intense training in hot conditions, or for races where performance matters. The key advantages of sports drinks are electrolyte replacement (especially sodium), easily digestible carbohydrates for sustained energy, and flavor that encourages drinking. However, sports drinks also contain calories and sugar that are unnecessary for shorter activities.
Water vs Sports Drinks
Short Runs (Under 60 min)
Water is sufficient. Your body has adequate glycogen stores and electrolytes for shorter efforts. Sports drinks add unnecessary sugar and calories for casual runs.
Long Runs (60+ min)
Sports drinks or electrolyte supplements become beneficial. They replace sodium lost through sweat and provide carbohydrates that sustain energy for extended efforts.
Hot Weather Running
Heat increases sweat rate and electrolyte loss. Even for moderate runs in hot conditions, electrolyte supplementation can improve performance and safety.
Race Day
For races, practice your hydration strategy in training. Many runners use a combination of water and sports drinks at alternating aid stations.
Runner's Hydration Tips
- For runs under 60 minutes, plain water before and after the run is usually sufficient
- For runs over 60 minutes, alternate between water and a sports drink with sodium
- Practice your race-day hydration plan during training to avoid surprises
- Know your sweat rate and aim to replace 50-80% of fluid lost during runs
- Consider salt tablets or electrolyte capsules as a calorie-free alternative to sports drinks

Frequently Asked Questions
Are sports drinks bad for you?
For active people, sports drinks serve a purpose during prolonged exercise. However, drinking them as casual beverages adds unnecessary sugar and calories. Save them for workouts over 60 minutes.
Can I make my own sports drink?
Yes, a basic homemade version is: 1 liter water, 1/4 teaspoon salt, 2 tablespoons sugar or honey, and a squeeze of lemon. This provides sodium, carbs, and flavor at a fraction of the cost.
How much should I drink during a run?
Aim for 400-800 mL per hour, adjusted for conditions and your sweat rate. Drink to thirst rather than forcing a set amount. Overdrinking is as dangerous as underdrinking.
Should I drink before a run?
Yes, drink 16-20 oz of water 2 hours before running, and another 8 oz about 15 minutes before. This ensures you start adequately hydrated without feeling waterlogged.
What about coconut water for running?
Coconut water provides potassium but has less sodium than sports drinks. It works for moderate runs but may not provide enough sodium for long, sweaty efforts.
