Replenishing your body with water is essential for marathon runners, before, during, and after their race.
Intense activity, especially when performed over a long duration, such as marathon running, depletes your body of fluids and electrolytes. Neglecting to replenish what you lose during a marathon affects your performance during the race, prolongs recovery, and can have a negative long-term impact.
If you have an upcoming marathon or you’re an event organizer responsible for keeping runners healthy and hydrated during the race, rapid hydration is essential. Here’s what you should know.
Why Do Marathon Runners Need to Hydrate Quickly?
Running a marathon is quite an undertaking. It takes extensive training, and you must be attuned to your body. You’ll likely work up a sweat, regardless of the weather. This means your body loses liquid fast during the event, and you’ll feel the effects quickly. Dehydrated runners have a higher risk of:
- Fatigue
- Cramping
- Reduced performance
- Overheating
- Headaches
It’s also important for marathon runners to be able to rehydrate quickly so there isn’t a significant impact on their race time.
Offering runners fast hydration options on race day is essential to help everyone perform at their best and have a healthy, fun race experience.
Tips for Staying Hydrated
There are several ways that marathon organizers can help runners hydrate quickly:
Start Early
Runners preparing for a race are likely focused on warming up their bodies before the run begins. This is a great time to encourage them to hydrate and “preload” their fluids for the race.
It’s also a good idea to begin hydrating in the days leading up to the race. When communicating with race participants, encourage them to drink consistently throughout the week so they begin race day with healthy fluid levels rather than trying to catch up at the last minute.
Early hydration reduces the need to drink excessively mid-race, which can cause unpleasant side effects and negatively impact your race time.
Use Electrolytes
You’ve probably seen on-the-go electrolyte packets recently. There are plenty of options, and they’re one of the most convenient ways to enhance hydration.
In addition to water, runners will lose sodium, potassium, and magnesium on race day. All of these electrolytes are important for maintaining balance and feeling your best.
Race organizers can include electrolyte options for runners to ensure they have everything they need to stay hydrated throughout the marathon.
Recognize Dehydration Symptoms
One of the best ways to ensure proper hydration during a marathon or at any time is to know the signs of dehydration. This way, you can take action early before symptoms worsen.
The most common signs of dehydration include:
- Dark urine
- Dizziness
- Fatigue
- Muscle cramps
- Thirst
Remember, you’re already dehydrated by the time symptoms arise, so it’s best to drink before you feel the need.
Rehydrate After the Race
There’s a lot that goes on after someone completes a marathon, and they don’t always feel like taking the time to drink water. They might also assume that if they stopped at water stations along the way, they are no longer at risk of dehydration once the race is over.
This isn’t the case. The body continues to lose water post-race, and it’s just as important in the hours and days after running a marathon to continue to replenish your body’s fluid supply.
Slow, Small, and Steady
When it comes to staying hydrated, it’s always better to avoid gulping down cups of water at a time. Instead, take small, frequent sips to keep hydrated without overwhelming the stomach. Gulping large amounts at once can lead to cramping or nausea.
Consistent sipping also helps maintain steadier electrolyte levels. Strategically spaced hydration stations make this approach easy and effective for participants.
