Why Trail Runners Crave Salty Food After Hours of Running

June 09, 2026 Hamza Boumezzough

After two, six, or ten hours on the trails, something strange starts happening.

The gels that tasted fine earlier suddenly feel impossible to swallow. Sugary drinks become sickly. Even thinking about sweetness can make your stomach turn.

And yet at the same moment, a bowl of salty broth, boiled potatoes, or a piece of bread with olive oil suddenly sounds incredible.

If you’ve experienced this during an ultra, long trail run, gravel ride, or ski touring day, you’re not imagining it. Craving salty food during endurance sports is one of the most common experiences in long-distance mountain culture.

And interestingly, it’s not just about sodium.

It’s also about appetite, digestion, flavour fatigue, and the psychology of eating during extreme efforts.

We explored part of this in our guide:
Why Do Energy Gels Make Me Feel Sick During Long Runs?

Why Do Runners Crave Salt During Long Runs?

The obvious answer is sodium loss.

During long efforts, especially in hot conditions, runners lose electrolytes through sweat. Sodium plays an important role in hydration, muscle function, and fluid balance, so naturally the body often starts seeking salt after several hours of exercise.

But that’s only part of the story.

Because most runners are not just craving sodium tablets. They’re craving actual savoury food:

soup
potatoes
noodles
bread
olives
crackers
cheese
salted watermelon

The deeper reason is usually a combination of:

sodium depletion
sweetness fatigue
digestive stress
appetite loss
emotional comfort

And the longer the race lasts, the more important those psychological factors become.

What Is Sweetness Fatigue?

Most sports nutrition is extremely sweet.

Energy gels, chews, drink mix, gummies, syrups - they all rely heavily on sugar because carbohydrates are fast and efficient fuel sources during endurance exercise.

The problem is repetition.

After several hours, many athletes experience something called flavour fatigue: the brain becomes overwhelmed by repeated sweetness, even if the body still desperately needs calories.

This is why runners often say things like:

“I physically cannot eat another gel.”

We discussed this more deeply in:

Because eventually the challenge becomes: not “How do I fuel?” but: “How do I keep eating?”

Why Savoury Foods Feel Better During Ultras

There’s a reason ultra-marathon aid stations around the world all start looking strangely similar after enough hours:

broth
boiled potatoes
rice
noodles
salty crackers
bread
soup

At UTMB aid stations in Chamonix, exhausted runners often stand silently holding cups of broth like it’s medicine. During ski touring days in the Alps, soup and bread become emotional reset moments. On long cycling adventures, riders stop for olives, cheese, sandwiches, and espresso.

These foods do more than provide calories.

They offer:

warmth
contrast
texture
comfort
familiarity

This fits perfectly into trail culture because trail running has always been closer to mountain refuge culture than hyper-optimized performance labs.

As we often say at Yanaa:

"food is part of the ritual, not just the function."

The Difference Between Energy Needs and Appetite

One of the biggest misunderstandings in endurance nutrition is assuming hunger and fueling are the same thing.

They’re not.

During long races, athletes often still need huge amounts of energy even when they completely lose the desire to eat.

That’s when fueling usually starts falling apart.

Common signs that appetite is disappearing during long runs

Symptom	What it often means
Gels seem disgusting	Sweetness fatigue
Dry mouth	Dehydration or over-sweet fueling
Nausea during climbs	Digestive stress
Craving salty foods	Need for contrast + sodium
Loss of appetite	Fatigue and sensory overload
Difficulty chewing	Heat, exhaustion, dehydration

This is exactly why many experienced ultra runners stop relying on just one type of fuel.

Instead, they rotate between:

gels
isotonic drinks
fruit
potatoes
savoury snacks
softer textures
real foods

Why Real Food Is Becoming More Popular in Trail Running

Over the last few years, more endurance athletes have started moving toward mixed fueling strategies.

Not anti-gel.

Not anti-performance.

Just more balanced.

This includes foods like:

rice cakes
olive oil
bananas
mashed potatoes
salty rice
savoury purées
broth
sushi
sandwiches

These foods can help reduce flavour fatigue and make fueling feel psychologically easier over long durations.

That’s also where products like Yanaa naturally fit into a trail fueling strategy:
not replacing every other fuel source, but acting as a savoury layer that helps runners continue eating when sweetness becomes difficult.

What Salty Foods Do Ultra Runners Actually Eat?

The answer is often surprisingly simple.

Common savoury foods during ultra races

Food	Why runners like it
Boiled potatoes	Easy carbs + salt
Broth	Warm, hydrating, comforting
Rice balls	Soft texture and stable energy
Olives	Salty and flavourful
Bread	Familiar and easy psychologically
Soup	Warmth and sodium
Crackers	Crunch and salty contrast
Savoury purées	Easier to eat late in races

Many of these foods exist naturally in endurance culture already. They’re not “trendy.” They’re simply foods athletes repeatedly return to when sweet fuel stops working.

Final Thoughts

Craving salty food during long runs is completely normal.

It doesn’t mean your fueling strategy failed. It doesn’t mean you’re weak. And it definitely doesn’t mean you suddenly stopped needing carbohydrates.

Usually, it means your body and brain are asking for something different:

contrast
warmth
texture
comfort
relief from sweetness

Because after enough hours in the mountains, endurance fueling stops being purely scientific.

It becomes deeply human.

And sometimes, the most important thing isn’t finding the “perfect” fuel.

It’s finding something you can still happily eat after six hours on the trails.

FAQ

Why do runners crave salty food?

Usually because of a combination of sodium loss, flavour fatigue, dehydration, and appetite psychology during long endurance efforts.

Why do gels stop tasting good during ultras?

Repeated sweetness over many hours can create flavour fatigue, making sugary foods difficult to tolerate.

What salty foods are best during trail races?

Popular options include potatoes, broth, rice balls, crackers, soup, olives, and savoury purées.

Do ultra runners eat real food?

Yes. Many endurance athletes combine sports nutrition products with real foods during longer races.

Can savoury foods help during long runs?

For many runners, savoury foods reduce sweetness fatigue and help maintain appetite during long efforts.
