How to Recover from Hitting the Wall in the Marathon

The biggest obstacle to completing 26.2 is hitting the wall in the marathon. So many runners have beautiful and perfect training cycles that are completely sabotaged when they come up against the marathon wall.

Hitting the wall, simply put, is when your body runs out of fuel for faster running. Your body slows down, your legs feel heavy, and it requires a lot of mental and physical effort to keep moving forward.

You can train to avoid hitting the wall in a marathon, but it’s almost a rite of passage for every marathoner. I’ve run 7 marathons in my life and I think I’ve hit the wall plenty of them!

As a result, I embarked on a quest on how to AVOID THE WALL! I’m sharing what I have learned.

The most common causes of hitting the marathon wall are:

1) going out too fast in the marathon (poor pacing)

2) not fueling enough during the race (poor fueling) and

3) not training enough at race pace and lactate threshold (poor training).

I want to help you avoid these mistakes! In this article I’m going to explain:

  • Why we hit the wall in the marathon and when it happens
  • How to avoid hitting the wall in the marathon
  • And what to do when you hit the wall (according to science!)

So, let’s get going!

What does it mean when hit a wall in a marathon?

The phrase “hit the wall” means encountering an obstacle that inhibits progress. When you hit a wall in a marathon, it’s difficult to keep moving forward, especially at your goal marathon race pace.

Hitting the wall happens in a marathon when your body has burned through all its glycogen stores in the liver and muscles which are the quickest and easiest fuel for your body to use to run. Your body then switches to burning fat as fuel which is a more difficult and slower process.

As a result, your body tries to conserve energy and protect itself by slowing you down. Your brain will signal the increased production of serotonin to inhibit control of your muscle fibers. This increases physical fatigue and mental exhaustion in which your brain tells you to stop running!

What does hitting the wall feel like?

The result of hitting the wall is sudden fatigue, like you’re running in water (hello! Aqua jogging!).

Hitting the wall happens around the 2-hour mark in the marathon or mile 20. Our glycogen stores last on average of up to 2,000 calories and we burn roughly 100 calories a mile.

If you’re running faster, you will burn through your stores faster too. Slower runners who burn mostly fat when running may not hit the wall at all.

How long does hitting the wall last?

Once you’ve hit the wall in the marathon, it is very hard to reverse it. Thus, hitting the wall lasts for the remainder of your marathon (about 6.2 miles or more!).

When you hit the wall, your body switches to conservation mode. It’s hard to get out of this mode because even if you’re taking energy gels, they still take about 20 minutes to digest. And by that time, you’ve burned through most of the fuel and it’s time to take another one to keep going!

How do you prevent hitting the wall in a marathon?

There are ways to avoid hitting the wall in the marathon. These ways are tied to proper pacing, fueling, and training.

  1. Proper pacing

Studies show that going out too fast in a marathon aka faster than you trained for is almost a surefire way to hit the wall in the marathon. Avoid this mistake!

Stay patient and smooth in your race. Follow your race plan and don’t get ahead of yourself. Running 26.2 miles is a really long way to go. And so many novice marathoners get fired up by the crowds and competition, that they run too fast and burn through their glycogen stores too soon.

  1. Proper fueling.

There are two main ways to avoid hitting the wall in the marathon when it comes to fueling: practicing fueling during your long runs and carb-loading ahead of the marathon.

Fueling your long runs: Your stomach is a muscle that needs to be trained to digest fuel while you run. This requires practice.

 Your stomach needs blood to help digest food and fuel. When you’re running, blood is diverted to your working muscles, so your stomach needs to do more with less.

The only way it can learn to do this is by practice. So, practice fueling on your long runs.

  • Aim to take a gel or 30 grams of carbs every 30 minutes with water. Drink sports drinks in between.
  • Start fueling early and often. Take a gel at the start line and then keep it up. Studies show that those who fuel earlier in a marathon run faster.

Carb loading before the marathon: Stocking your glycogen stores so you have more fuel to burn takes at least 3 days. Don’t rely on a pasta dinner the night before to do this. In fact, that may make you feel sluggish in your marathon.

  • Three days out from your race, start nearly doubling your carb intake at every meal. Stick to simple carbs like oatmeal, bagels, fruit, and crackers.
  • Start drinking electrolytes throughout the day, aiming for about 80 ounces.
  • Get up two hours before your marathon and eat a high-carb breakfast. Then eat a high-carb snack of about 250 calories an hour before the race.
  1. Proper training.

The best way to avoid hitting the marathon wall is to do long runs every week in your training. This teaches your body how to store and use glycogen efficiently. You’ll also build mental and physical strength.

Your long run should be about 30 percent of your weekly mileage, more if you’re a low mileage runner, and run at a conversational pace.

You should include at least one really long run in marathon training in your peak week. This long run will be close to your marathon finish time, but less if your marathon finish time is more than 4 hours (in general, capping at 3:30 for 4-hour marathoners and capping at 4 hours for 5+-hour marathoners).

5 Tips to Recover from Hitting the Wall in the Marathon

What should you do when you hit the wall in a marathon? Whatever you do, you should NOT give up! There are mental strategies and fueling strategies that can help you get past the wall in the marathon. You may not be able to return to you goal marathon pace but you can keep going, and possibly have a finishing kick.

I dug into the research to reveal tips to recover from hitting the wall in your marathon.

Continue fueling.

Unless you are experiencing GI distress, continue your marathon fueling. It may be hard mentally to keep taking in gels, water, and electrolyte drinks but it will help. You cannot fully reverse hitting the wall, but you can slow the effects.

The quickest absorbing energy gels take 15 to 20 minutes to noticeably have an impact, 60-75 minutes to absorb fully, and peak around 30-45 minutes. Meanwhile, you burn through a gel in about 30 minutes. (Though your metabolism and absorption rates may be slower in glycogen depletion). This means that you will be using what you take in, but the gels will have a cumulative effect.

Therefore, taking in energy gels and drinks will keep you going and may even allow for you to have a finishing kick in your marathon. So, keep up the fueling!

Distract yourself.

Research finds that disassociative thinking (thoughts unrelated to the marathon you’re running) may help you recover from hitting the wall in the marathon.

Some thoughts include making your grocery list or planning your perfect vacation in your head and going through the steps of how to make that happen.

Make a friend.

Studies also show that social support can help you move past the wall in a marathon. So, even if it takes a lot of effort, start talking to a runner around you. Tell them good job, or make a comment about the course, weather, or crowds.

You can also give a spectator a high-five or thank them for cheering you on. This positive energy will give you a positive feedback loop that will help override the negative thoughts swirling in your brain.   

Positive self-talk.

Studies support that positive self-talk reduces negative thinking when you hit the marathon wall. Find a mantra such as “I am strong” or “This is tough, but I’m tougher” to keep you going.

A good mantra should be something simple that is easy to repeat in a rhythmic way, matching your footsteps. It should also reconnect with your why.

Is your why to show your kids what it means to be courageous? Is your why to be healthy for your family? Is your why to teach your children what it means to work hard towards a goal?

Nail down your mantra before you begin your race. And have it at the ready when things get tough. At this point, it can also be helpful to not look at your GPS watch as it may give you negative feedback. Instead, focus on one positive good thing, even if that is just that your left forearm feels good.

Reframe your goals.

If you had a time goal and that seems impossible, forget about it. Reframe your goal to the current moment: focus on the mile you are in. Put one foot in front of the other. Listen to your breath. And reaffirm to yourself what a tough person you are.

Running a marathon is no easy feat. And you’re doing it! And you will cross that finish line stronger and better for it!
