Trail running has exploded in popularity over the last few years, and once you’ve spent a few hours running through forests, mountain ridges, or alpine trails, it’s easy to understand why.
But trail running is very different from road running. It's not just the type of terrain you are running on, but also the culture of the sport.
For beginners, trail running can feel overwhelming at first:
What shoes do you need? What do trail runners eat? How do you fuel for long mountain runs? What’s the difference between trail running and road running? What on earth is gravel running?!
This guide breaks down everything you need to know about trail running, including gear, clothing, nutrition, hydration, and how experienced runners fuel long days in the mountains without burning out on sweet gels.
What Is Trail Running?
Trail running is done on natural terrain instead of paved roads.
Mountain trails, forest paths, gravel tracks, alpine terrain, technical singletrack - anything other than asphalt!
Unlike road running, trail running is less about pace and more about effort, endurance, elevation, and adaptability.
One hour on a flat road can feel completely different from one hour climbing technical mountain trails.
Some trail runs are short and fast. Others turn into full-day adventures with steep climbs, changing weather, and hours spent moving through remote terrain.
For many runners, that’s exactly the appeal.
Trail running combines fitness, adventure, nature, and endurance in a way road running rarely does.
Trail Running vs Road Running: What’s the Difference?
One of the most searched questions online is:
“What’s the difference between trail running and road running?”
The answer goes far beyond the surface.
Terrain Changes Everything
Road running is predictable.
Trail running is constantly changing.
You’re adjusting to rocks, mud, roots, climbs, cambers, and descents.
That means your muscles, joints, and stabilisers work differently throughout the run.
Trail running also tends to involve much more elevation gain, which changes pacing and energy demands completely.
Trail Running Is Slower, But... HARDER
A common beginner mistake is comparing trail pace to road pace.
On technical trails, pace becomes almost irrelevant.
A steep mountain climb might be physically harder than running fast on roads, even if your speed drops dramatically.
That’s why experienced trail runners focus more on:
- Time on feet
- Heart rate
- Elevation gain
- Perceived effort
- Nutrition and hydration
Not just pace per kilometer.
Trail Running Requires More Than Just Fuel
One of the biggest differences between road running and trail running is fueling.
Long trail runs, most often measured by distance can vary from 5km to 150km, and in some cases more than 500km.
That creates a completely different nutritional challenge.
The longer the effort gets, the more difficult eating becomes.
And this is where many trail runners struggle.
What Do You Wear for Trail Running?
Another common question beginners ask:
“What should I wear for trail running?”
The answer depends on terrain, weather, and distance, but there are a few essentials every trail runner should know.
Best Trail Running Shoes for Beginners
Trail running shoes are designed specifically for uneven terrain.
Unlike road shoes, they offer:
- Better grip
- More traction
- Extra foot protection

The best trail running shoe depends on where you run most often.
Essential Trail Running Clothing
Trail weather changes quickly, especially in the mountains. so good trail running clothing should prioritise:
- Breathability
- Lightweight protection
- Packability
- Moisture management
- Layering
Trail Running Clothing Essentials
Moisture-Wicking Running Top
Avoid cotton completely.
Technical fabrics dry faster and help regulate body temperature.
Here at Yanaa we love natural fibres - wool being our favourite.
Trail Running Shorts or Tights
Look for:
- Storage pockets
- Anti-chafing comfort
- Lightweight materials
Chris, Yanaa's co-founder is known for his short shorts...
Waterproof Running Jacket
One of the most important pieces of trail gear for mountain conditions. A fully waterproof minimalist jacket is invaluable. The Gore-Tex Shakedry products are Chris' favourite.
Trail Running Vest or Pack
Longer trail runs usually require carrying:
- Water
- Food
- Layers
- Phone
- Emergency gear
Its best to try them on in person before you buy to make sure they fit your body type.
What Do Trail Runners Eat?
This is where trail running becomes really interesting.
Because, unlike shorter road races, trail running nutrition becomes a major part of performance.
If you check Google, one of the biggest search terms in endurance sports right now is:
“Best food for trail running.”
The reason is simple: most runners eventually realise that surviving on sugary gels for hours becomes incredibly difficult.
You can't fuel trail running like you would fuel a marathon.
The Biggest Problem With Trail Running Nutrition
At the beginning of a long run, gels usually feel easy.
A few hours later?
Not so much.
Sweetness fatigue is one of the biggest issues in endurance fueling.
After hours of sweet sports nutrition:
- Appetite drops
- Sweet flavours become overwhelming
- Stomach discomfort increases
- Eating starts feeling forced
Most long-distance runners recognize the moment instantly: “I can’t eat another gel.”
And once fueling starts falling apart, energy often follows.
That’s why more runners are searching for:
- Real food for trail running
- Savoury trail running nutrition
- Easy-to-digest ultra running fuel
- Alternatives to energy gels
What to Eat Before a Trail Run
Good trail running nutrition starts before the run begins.
Best Pre-Run Meals for Trail Running
For long trail runs, runners usually want:
- Carbohydrates for energy
- Moderate protein
- Easy digestion
- Hydration
Popular pre-run meals include:
- Oatmeal with banana and honey
- Rice and eggs
- Toast with nut butter
- Yogurt with fruit
- Pasta or rice meals before ultra-distance efforts
The goal is stable energy without digestive stress.
What to Eat During Long Trail Runs
During longer efforts, runners need consistent fueling. Most endurance athletes aim for regular carbohydrate intake every hour through:
- Synthetic Carbohydrate Products: gels, bars, chews
- Natural Carbohydrate Rich Foods: bananas, raisins, sweet potatoes, rice balls.
- High Carb Drinks: synthetic products, or natural juices.
- Real foods: sushi, a roast chicken, tuc biscuits, or Yanaa.
But here’s the reality most runners discover eventually:
The challenge isn’t only energy.
It’s maintaining the desire to keep eating.
Why More Trail Runners Are Switching to Savoury Fuel
This is one of the biggest shifts happening in endurance nutrition right now.
Instead of relying entirely on sweet products, many runners are adding savoury fuel into their nutrition strategy.
Because after several hours in the mountains, most people naturally start craving:
- Salt
- Comfort food
- Real ingredients
- Texture variation
- Less sweetness
That’s exactly the problem Yanaa was designed around.
Rather than positioning itself as another sugary sports product, Yanaa focuses on becoming:
“The savoury layer in your fueling system.”
The idea is not to replace gels completely.
It’s to help runners continue fueling during long efforts when sweetness becomes difficult to tolerate.
That moment is incredibly common in endurance sports:
“When sweet fuel stops working.”
And once that happens, many athletes stop eating enough altogether.
Why Real Food Matters During Long Trail Runs
Trail running culture has always been closer to real food than many other endurance sports. Spend enough time around ultrarunners and you’ll see aid stations full of:
- Potatoes
- Rice balls
- Broth
- Sandwiches
- Savoury snacks
- Warm food
- Salted watermelon
Because over very long efforts, food becomes psychological as much as physical. Yanaa leans into that idea with:
- Chef-made recipes
- Savoury flavors
- Easy-to-digest texture
- Portable real-food nutrition for endurance athletes
The goal is simple:
Help runners keep eating consistently so energy levels stay stable longer.
Best Hydration Tips for Trail Running
Hydration during trail running depends on:
- Heat
- Elevation
- Sweat rate
- Duration
- Terrain
Most trail runners need a combination of :
- Water
- Electrolytes - in particular, sodium
One of the biggest beginner mistakes is drinking only water during long runs without replacing sodium, because that can lead to:
- Fatigue
- Nausea
- Cramping
- Poor recovery
Hydration and fueling always work together.
Beginner Trail Running Tips
If you’re starting trail running for the first time:
Slow Down
Trail pace is naturally slower.
Walk Climbs
Even elite ultrarunners hike steep terrain.
Practice Fueling Early
Never wait until you feel empty.
Test Nutrition in Training
Race day is not the moment to experiment.
Prioritize Comfort
Good gear and good fuel matter more than speed early on.
Respect Long Mountain Days
Conditions change fast on trails.
Trail Running Is About More Than Running
Trail running isn’t just road running in nature. It’s a completely different relationship with movement, endurance, food, and effort. The longer the runs become, the more important fueling becomes too. Not just calories, not just carbohydrates. But food you can actually keep eating after hours on the trail. That’s why the conversation around endurance nutrition is changing.
More runners are looking for:
- Real food trail running nutrition
- Savoury alternatives to gels
- Better digestion during ultras
- Fuel that feels sustainable over long mountain days
And that’s exactly where Yanaa fits:
helping athletes fuel long efforts without reaching the point where eating feels impossible.
