Gatorade Endurance Formula is scientifically formulated to meet the specific needs of endurance athletes. It contains a five-electrolyte blend including nearly twice the sodium (200 mg) and more than three times the potassium (90 mg) compared to original Gatorade Thirst Quencher. Drink Gatorade Endurance Formula to help sustain hydration, help maintian proper fluid balance and help replace key electrolytes lost in sweat during long distance training and racing.

Fuel your pre-race training with Gatorade Endurance Formula and other Gatorade Endurance products by finding them at a store near you or ordering online.

Taking the right kind of fuel is critical to an endurance athletes’ success. Get ready for race day by reviewing hydration tips from Gatorade below or learn more at gatorade.com/endurance.

Hydration Tips for Endurance Athletes

  • Endurance athletes, especially when training or racing >2h or those who have high sweat losses, should replace both fluid and sodium during exercise. To estimate if you are a “salty sweater,” look for white residue on dark colored clothing after a training session
  • Know your sweat rate to customize a plan to meet your unique needs
  • You should determine your individual sweat rate and consume fluids with sodium to minimize body weight changes during training and racing. To determine your sweat rate, measure body weight before and after a training session in the same environment as the race and keep track of all the fluid consumed. A rough estimate of sweat rate can be obtained by using the following equation: Sweat Rate (L/h) = (weight loss – fluid intake (L))/exercise time (hours) An automated calculator is available here at the Gatorade Sports Science Institutes Website.
  • Answering “yes” to any of these questions may indicate inadequate hydration: Am I thirsty? Is my urine a dark yellow color? Is my body weight noticeably lower than yesterday?
  • You should be sure to drink enough fluid to prevent dehydration without over-drinking. Dehydration may strain the cardiovascular system and increases body temperature, which increases the risk of heat illness. However, endurance athletes who over-drink in relation to sweating could be at risk for a rare but very serious condition called hyponatremia (low blood sodium concentration). Consuming beverages with sodium during training and racing may help maintain blood sodium levels.
  • Mix and match products to find the right combination of solids and fluids to meet both your carbohydrate and fluid needs

Recommended Carbohydrate Intake During Exercise

 
Duration Carbohydrate Amount Notes
< 30 Minutes None Required
30-75 Minutes Very Small Amounts Mouthrinse appropriate
1-2.5 Hours 30-60 g/h Rapidly used sources such as sucrose, glucose, and maltodextrin
> 2.5-3 Hours Up to 90 g/h Use a blend of glucose & fructose
  • Use sports drinks to provide fluid and electrolytes
  • It is possible to train the gut! If you are currently consuming less than the recommendations, try to gradually increase intake during training to reach recommended levels. 
  • Practice your race strategy in training and make sure you can tolerate your race nutrition without problems
