About Hydrathon – Born from a passion for running

Hydrathon was born from a simple idea: runners deserve hydration products they can blindly trust. During a training session or race, you want to be able to fully focus on your pace, your breathing, and the kilometers ahead. You don't want to be distracted by a leaking soft flask, an uncomfortable running vest, or equipment that fails you when it matters most.

It was precisely this conviction that led to the founding of Hydrathon.

Not by a large international sports brand, but by an avid (trail) runner who repeatedly encountered the same problems. After hundreds of training hours on asphalt, forest paths, hills, and mountain trails, one thing became increasingly clear: good hydration gear should actually be invisible. You only notice that a product is good when you no longer have to think about it at all while running.

That is exactly what Hydrathon stands for.

Built by a runner, designed for runners

Every kilometer we run provides new insights. During long endurance training sessions, fast interval sessions, half marathons, marathons, and ultra-trails, we discovered what is truly important for runners.

A soft flask must:

• fit comfortably in the hand;
• stay firmly in a running vest;
• not leak while drinking;
• be refillable quickly;
• not impart an unpleasant plastic taste;
• be easy to clean;
• and, above all, last for years.

That sounds obvious, but in practice, not every soft flask meets all these requirements.

That is why we develop products that we ourselves confidently use during training and races. No unnecessary features or complicated designs, but smart solutions that contribute to a better running experience.

Our mission

Our mission is simple:

To help runners perform optimally with reliable hydration products that always do what they are supposed to do.

We believe that good sports equipment is not a luxury, but a tool with which every runner can train more comfortably, efficiently, and with more pleasure.

Whether you are just starting with running or have been running ultramarathons for years, sufficient hydration is essential. Good hydration supports your performance, helps reduce fatigue, and ensures that your body continues to function optimally during both short and long exertions.

That is why we develop products that help you easily carry your drinks, without extra weight or unnecessary discomfort.

Developed for every runner

At Hydrathon, we believe that every runner has different needs.

A recreational runner who runs five kilometers three times a week has different requirements for their equipment than someone preparing for a marathon or a 100-kilometer ultra-trail.

That is why our collection consists of multiple sizes of soft flasks.

Soft Flask 150 ml

Our smallest soft flask is ideal for:

• fast training sessions;
• short races;
• 5 km and 10 km races;
• carrying energy gels or concentrated sports drinks.

Due to its compact size, you hardly feel like you are carrying it.

Soft Flask 250 ml

The 250 ml soft flask is our most versatile version.

Perfect for:

• daily training sessions;
• half marathons;
• longer interval training;
• recreational trail runs.

This volume offers an excellent balance between weight and sufficient hydration.

Soft Flask 500 ml

For long adventures, extra capacity is essential.

Our 500 ml soft flask is designed for:

• marathons;
• ultramarathons;
• trail running;
• mountain treks;
• long endurance training.

As the flask shrinks while you drink, it remains comfortable against the body and prevents annoying sloshing of water.

Why do runners choose Hydrathon?

We don't develop products because we can, but because they solve a problem.

Every choice in our products is made with practicality as the starting point.

Lightweight design

Every gram counts when running.

Our soft flasks are designed to be as light as possible without compromising on robustness or durability. Even when fully filled, the flask remains comfortable.

Reliably leak-proof

Nothing is more annoying than a wet running vest or sticky sports drink in your pockets.

That is why we use a reliable bite valve that only releases water when you actually drink.

No leaks.

No waste.

No distraction.

BPA-free materials

Health comes first.

Our soft flasks are made from high-quality BPA-free materials that are safe for daily use.

In addition, water and sports drinks remain neutral in taste, without an unpleasant plastic odor.

Compatible with most running vests

You don't need to buy a completely new running vest.

Our soft flasks are designed to fit most popular running vests and hydration systems.

Whether you train on the road or in the mountains, you can continue to use your trusted gear.

Easy to clean

A soft flask should not only be pleasant to drink from but also easy to maintain.

That is why our flasks have a wide opening, making cleaning quick and easy.

This prevents unpleasant odors and ensures that every sip tastes fresh.

Developed for real kilometers

Every Hydrathon soft flask is tested under the conditions for which it is intended.

Not just behind a desk or in a laboratory, but during real training sessions.

On:

• asphalt;
• gravel;
• forest paths;
• hills;
• mountain passes;
• muddy trails;
• warm summer days;
• rainy winter training.

Only when a product proves itself in practice does it earn a place in our collection.

Our vision on running

For us, running is not just about speed or personal records.

It's about freedom.

About going out early in the morning while the world is still quiet.

About disappearing into nature for hours.

About challenging yourself during a marathon.

About that last climb during a trail run.

About the feeling you get when you can go further than you thought.

We want to make products that contribute to that experience.

Not by drawing attention to themselves, but by silently doing their job.

More than just a webshop

Hydrathon wants to be more than just a place where you buy a soft flask.

We are building a community for runners who like to share knowledge about:

• running training;
• trail running;
• hydration;
• nutrition;
• equipment;
• races;
• recovery;
• injury prevention.

Through our blogs and guides, we help runners to be better prepared at the start, regardless of their level or goal.

Our promise

When you choose Hydrathon, you choose products developed from practical experience.

No marketing talk, but functional products that do what they are made for:

to help you stay hydrated comfortably, reliably, and without distraction during every kilometer.

That's what Hydrathon stands for.
