How do you start your first ultra run in 2026?

Trail Guide 2026

Covering distances greater than the classic marathon of 42.195 kilometers demands a great deal of physical endurance and mental strength. At an ultra run it is not about a fast pace. Factors such as respect for the surface, a well-thought-out nutrition plan, and the right technical equipment determine your success. The training methods and materials for Trail running have improved significantly in recent years, making extreme distances achievable for motivated runners. The switch from paved roads to unpaved paths drastically changes the load on your body. You will encounter elevation changes, varying surfaces, and fatigue that builds up over many hours.

A safe and structured approach forms the foundation for the transition to ultra-distances. By shifting the focus from pure speed to energy-efficient running, you spare your joints and build strong stamina. This optimally prepares the body for the specific physical challenges of running in nature.

What is an ultra run? Beyond the 42.195 km mark


Officially, any race longer than a classic marathon is an ultra run. In practice, most runners start with a distance of 50 kilometers. These routes often run over technical forest paths, rocky mountain trails, or loose sandy paths along the coast. While a road marathon is primarily about your time per kilometer, the Trail running for altitude, terrain knowledge, and energy management.

Running fifty kilometers in nature presents challenges you won't easily encounter on the road. Steep slopes force you to walk, while technical descents demand extreme concentration and quick footwork to spare your ankles. Changing weather conditions complete the picture. Speed ​​gives way to efficiency, where smart energy distribution determines whether you reach the finish line.

Building an aerobic base and back-to-back endurance runs


Preparing your muscles and joints for the prolonged strain of an ultra run requires a patient build-up of training mileage. The foundation of any training plan consists of running at a low intensity. By training at a pace where you can still easily talk, your body learns to use fats more efficiently as fuel. This allows you to conserve precious carbohydrate reserves for the later stages of the run.

A proven training method for ultra-athletes is the so-called 'back-to-back' endurance run. Instead of one long 40-kilometer run, which carries a high risk of injury and exhaustion, you divide the distance over two consecutive days. For example, you run 25 kilometers on Saturday and 15 kilometers on Sunday. This teaches your body to perform on tired legs, without the heavy physical impact of one extremely long training session.

Pro Trail Tip

During your training sessions, consciously practice walking on steep sections. This brisk walking (power hiking) keeps your heart rate low and saves your thighs for the flat parts and descents.

Essential equipment for Trail running


When you spend six to twelve hours in nature, the right equipment is of vital importance. Unlike road races with frequent aid stations, you are largely on your own during an ultra run. A well-fitting trail vest distributes the weight of your drinks, food, and mandatory safety gear evenly across your upper body. This prevents chafing and keeps you stable on challenging trails.

The choice of shoes is also crucial. Trail running shoes for long distances have enough Cushioning necessary to absorb the constant shocks. In addition, a coarse tread on the Outsole for grip on mud, wet grass, and loose stones. Preferably choose a model with a wider toe box. Your feet swell while walking, and extra room prevents painful blisters and bruised toenails.

Trail vest contents 10 - 12 liters (for Mandatory gear)
Sole tread depth 4 to 6 mm (for grip on various surfaces)
Water capacity At least 1.5 liters (soft flasks and water bag)

Nutrition and hydration on the go


Running for hours on end completely depletes your energy reserves. To maintain your pace and prevent a sudden energy crash, it is necessary to rest regularly. Carbohydrates to replenish. During an ultra run, your digestion is under pressure because less blood flows to your stomach and more to your working muscles. Therefore, choose easily digestible food. Energy gels, Sports drinkand soft, solid foods such as bananas, dried fruit, or salted potatoes work well, because they are absorbed quickly without straining your stomach.

Good hydration revolves around the balance between fluids and minerals, and therefore not solely about drinking water. You lose important salts through sweat that are necessary for your muscles to function properly. Drinking too much pure water without replenishing these minerals thins your blood. This can lead to muscle cramps, nausea, and severe fatigue. Therefore, add Electrolytesadd tablets or powder to your water bottles to the Sodiumto maintain balance. This ensures your muscles continue to function properly and your body absorbs fluids better, preventing dehydration on remote trails.

Carbohydrate intake per hour 60 - 90 grams (240 - 360 kcal)
Guideline for fluid intake 500 - 750 ml per hour (depending on the heat)
Sodiumneed 300 - 600 mg per hour (for muscle cramps)

Mental strategy: breaking down the route


Physical training prepares your muscles and lungs, but your mental attitude determines whether you reach the finish line. Standing at the start of a 50-kilometer trek and thinking about the total distance is mentally grueling. Experienced UltrarunnerTherefore, they break the route down into smaller sections. By focusing only on the next part each time, you prevent your brain from becoming overwhelmed by the magnitude of the challenge. This lowers your stress level and helps you distribute your energy better.

Divide the course into manageable stages, such as aid stations or clear landmarks in the landscape. Celebrate a small victory at each station. Take a brief moment there to recharge, eat and drink according to plan, and only then turn your attention to the next section. By viewing a 50-kilometer run as five separate 10-kilometer stages, a grueling challenge transforms into a series of achievable goals. This approach provides peace of mind and helps you stay focused when physical fatigue sets in.

Mental tip

Break the race down by aid station. As soon as you leave a station, your only goal is to reach the next one. Only think about the finish line when you reach the very last checkpoint.

Dealing with elevation gain and technical descents


Unlike road marathons, trail routes are rarely flat or even. You will encounter steep climbs and technical descents that require a specific technique.If you try to maintain your normal running pace uphill, your heart rate shoots up quickly and you become exhausted fast. Walking briskly with short, deliberate steps – leaning forward and perhaps placing your hands on your thighs – is the most efficient way to climb. This technique spares your calves and Achilles tendons, so you conserve energy for the flatter sections.

Descending requires at least as much concentration. Gravity pulls you down automatically, but landing heavily on your heels acts like a hard brake. This deals heavy blows to your ankles, knees, and lower back. To descend safely and spare your muscles, keep your center of gravity slightly forward. Take short, quick steps and land on your midfoot. This allows your thighs and glutes to absorb the impact smoothly. Keep moving in a relaxed manner and look a few meters ahead to avoid tree roots, stones, and slippery patches in time.

In a back-to-back endurance run, you spread the training kilometers over two consecutive days (for example, 25 km on Saturday and 15 km on Sunday). This teaches your body to perform on already fatigued legs without the heavy physical impact and risk of injury of one extremely long training session.

Why do you have to walk (power-hiking) during an ultra run? +

Trying to run on steep slopes causes your heart rate to peak quickly and exhausts your muscles. By consciously choosing to walk briskly (power hiking), you keep your heart rate low, spare your thighs, and save energy for the flatter sections and descents.

Why is drinking only water not sufficient during an ultra? +

When sweating, you lose not only fluids, but also important minerals such as SodiumIf you drink exclusively pure water for hours, the dilutes Sodiumconcentration in your blood. This can lead to muscle cramps, nausea, and severe fatigue. Adding Electrolytes helps maintain fluid and salt balance.

Why is extra toe room (toe box) so important in ultra-trails? +

During hours of exertion and many kilometers, more blood flows to your feet, causing them to swell slightly. Trail running shoes With a wider toe box, your toes have room to expand, which prevents pinching pressure points, blisters, and bruised toenails on long descents.

What is the best technique for a technical descent without straining your joints? +

Do not slow down by landing heavily on your heels, as this puts hard strain on your knees and lower back. Keep your center of gravity slightly forward, take short, quick steps, and land on your midfoot. This allows your thighs and glutes to absorb the impact in a natural, springy manner.
