If you’ve bonked in your marathon or experienced muscle cramps when running, I recommend taking a hard look at your hydration while running. Chances are you needed to level up your electrolyte intake.

Hydration is essential for runners.
Hydration is essential for the health and performance of runners.

I recently discovered this after speaking with many registered dietitians and doing research. Taking energy gels and water during runs is not enough—especially if you are sweating.

Chances are you need to take energy gels with an electrolyte drink or take a sports drink for runners that include electrolytes and carbohydrates. If you take energy gels with a hydration drink for runners, make sure the two go together otherwise they can turn to sludge in your stomach.

What? Yes, fueling for long-distance running can be complicated! But I try to simplify it in my guide for hydration for runners here and below in my review of the best electrolyte drinks for runners.

This comes with one big caveat: you have to TRY your fueling plan first! Everyone’s stomach is different—especially when running at intensity over long periods of time. So, try, try, TRY your energy gels and sports drinks for runners combos throughout your training.

Okay, so in this article, I’m going to cover:

  • What are electrolytes and the benefits of electrolytes for runners
  • When to use sports drinks when running
  • What hydration drinks for runners should have and NOT have
  • Sports drinks and energy gel tips
  • The 6 best electrolyte drinks for runners

What are electrolytes?

Electrolytes are minerals that have a positive or negative electrical charge when dissolved in water. This helps them regulate chemical reactions in the body like nerve signaling and muscle contractions and maintain fliud balance inside and outside your cells aiding your body in oxygen-rich blood transport to your working muscles.

Electrolytes also support key functions in the body such as muscle and heart contraction and blood pressure, for example.

Why do runners need electrolytes when running?

Runners need electrolytes when they’re running for athletic performance and overall health. 

According to registered dietitian Megan Robinson, “sodium has an important role in the body of maintaining the osmolality of the blood, which in turn keeps the balance of water between the inside and the outside of our body’s cells. It also plays an important role in regulating the overall amount of water in the body, by influencing both how much how is lost or retained by the kidneys, and our thirst and desire to drink.”

Electrolytes help maintain our hydration status and keep our blood flowing, joints lubricated, and muscles contracting. An electrolyte imbalance can lead to dehydration, muscle fatigue, increased perceptions of exertion, and poor performance, for example.

According to Robinson, the benefits of electrolytes for runners include:

  • nerve signaling,
  • muscle contractions,
  • bone health,
  • hydration,
  • pH level balance,
  • water balance in your body,
  • heart contractions
  • waste product shuttling
  • key brain function support
  • the elimination waste from your cells,
  • and making sure your nerves, muscles, heart, and brain all work the right way.

When should you take electrolytes?

Runners should take electrolytes before, during, and after running.

In short, runners should aim to drink:

  • a sports drink of 16 ounces before a run with 400 mg of sodium.
  • aim for 12-200 ounces of a hydration drink with electrolytes (400 mg of sodium) per hour of exercise during running,
  • and refuel with an electrolyte drink of 16 ounces (400 mg of sodium) after running.

Check out my hydration for runners guide here for details. Note that factors such as sweat rate and weather will impact how much liquid and electrolytes you need for your running.

What kind of electrolytes do runners need?

Pin these sports drinks for runners for later!

The electrolytes runners need include sodium, chloride, potassium, magnesium, calcium, and phosphate:

  • Sodium. Sodium, or salt, helps the body hold on to water, keeping you hydrated. The more you sweat, the more sodium you lose which can lead to dehydration, muscle cramping, and poor performance. This is obviously important for runners as dehydration can cause muscle cramping and hurt performance. Sodium is lost in sweat.
  • Chloride. Chloride helps maintain fluid balance, blood volume, blood pressure, and body fluid pH levels. It’s also lost in sweat.
  • Potassium. Potassium is key for muscle contraction and helps blood pressure regulation, cell, and heart function, and bone loss production, warding off kidney stones.
  • Magnesium. Magnesium supports nerve and muscle function, and a healthy immune system regulates the heartbeat, keeps bones strong, and balances blood sugar levels.
  • Calcium. Calcium is vital for strong bones, helping muscles move, nerve signaling, the transport of blood vessels, and the release of hormones necessary for key bodily functions. 
  • Phosphate. Phosphate is important for nerve function, bone and teeth modeling and repair, and muscle contraction.

Note: Sodium is the one that can be the hardest to replace. Large amounts of the other electrolytes are not needed for running and performance.

How do I drink electrolytes while running?

You can drink an electrolyte drink when running by stashing a bottle on your route, wearing a hydration vest, or carrying a handheld bottle like this Nathan one.

For races like marathons, you can also grab TWO cups at water stops.

For the CIM marathon, I ran with one 12-ounce Nathan bottle with NUUN hydration drink and grabbed another at the halfway point from my husband. (I took Maurten gels every four miles).

Should I drink a sports drink with energy gels?

In most cases, you do not want to drink a sports drink with an energy gel because it will cause stomach distress. However, your body needs the carbs from the energy gel and the electrolytes from the sports drink. Energy gels don’t have enough electrolytes to support your running while many sports drinks don’t have enough carbohydrates. So, in many cases, you need to include both in your marathon fueling.

Your fueling options to take both are:

  • Take an energy gel that’s a hydrogel like Maurten or Science in Sport (SIS) with a sports drink.
  • Take a normal energy gel with water and then take a sports drink several minutes or a mile after. Alternate drinking water and a sports drink.
  • Drink a sports drink that has both carbs and electrolytes like Maurten, Gnarley Fuel2o, or Skratch.
  • Use an energy gel like Huma Gel+ that has both electrolytes and carbs.
  • Use an energy gel with water and take salt tablets or salt chews with water in between gels.

What should sports drinks for runners include?

Sports drinks for runners including electrolyte tablets or electrolyte hydration powders should include sodium, chloride, potassium, magnesium, calcium, and phosphate.

If you are drinking a sports drink for both its electrolytes and carbohydrates, then it should also include glucose (sugars).

These hydration drinks should have little to no artificial ingredients, chemicals, and added sugar.

7 Best Electrolyte Drinks for Runners

Here are the best drinks with electrolytes for runners available today. I chose them based on the quality of their ingredients, taste, efficacy, and reputation.  

Note: that I highlight the sodium contents as this electrolyte is the one that is most lost while running and the hardest to replenish. Aim for a minimum of 200 mg an hour.

Also: Remember that the ones that include carbs can be used in place of gels (Skratch, Gnarley, and Maurten). You fuel with only the drink.

All these products include other crucial electrolytes for runners.
