Arduua – Who We Are

FOR PASSIONATE TRAIL RUNNERS WORLDWIDE!

Arduua is a global trail running community for passionate trail and ultra-trail runners who embrace challenge, dream big, and commit to personal growth — all while nurturing a deep connection to the mountains.

We believe the mountains are for everyone — not just elites. Trail running is an open path for all, no matter your starting point, your experience, or where in the world you live.

Our runners come from diverse backgrounds and cultures, united by a shared love for nature and the determination to improve. Team Arduua stands as an international race collective, competing worldwide almost every weekend, all following the same structured training system, wearing the same apparel, and representing one purpose: transformation through trail.

Arduua offers a comprehensive global online coaching platform, delivering personalized training and expert guidance through an international coaching team. We also create opportunities for race meet-ups, immersive training camps, and a global team culture that connects athletes far beyond the finish line.

Our coaches are specialists in Trail Running, Skyrunning, and Ultra-trail, holding degrees in Sports Science and providing high-quality coaching in both Spanish and English.

Beyond coaching, we have developed the eminent Arduua Trail Apparel brand — meticulously crafted using high-performance, breathable, and lightweight materials that deliver unparalleled functionality for trail running.

Every garment is designed by trail runners, for trail runners, with a focus on durability, comfort, and performance across the toughest terrains. Our signature products — trail running skirts and trail running shorts — offer unique features and designs that no other brand provides, blending technical excellence with a distinctive Arduua style. Hailing from Spain, our apparel combines advanced fabric technology with refined design, ensuring that every piece performs flawlessly while representing the pride of our community.

Arduua – the story of a name

The name Arduua is rooted in the Latin word Ardua, meaning “steep” — a nod to the relentless climbs and challenges that define trail and ultra-trail running.

Ardua = Steep, in Latin

Arduus = Steep, demanding, unattainable

Arduous = Hard to achieve

Arduua = The profound joy when you achieve your goal

At Arduua, this word embodies more than just the physical ascent. It reflects the emotional and mental journey every runner takes — the discipline of training, the courage to start, the grit to persevere when it hurts, and the euphoria of crossing the finish line.

We chose Arduua because it captures the essence of transformation. Picture standing at the base of a mountain you’ve dreamed of summiting — your heart racing, your body primed, your mind focused. The climb is long, steep, and at times unforgiving. Each step is a test of willpower. And then, finally, you reach the summit: the view stretches endlessly, your lungs fill with mountain air, and you feel unstoppable.

That’s your Arduua moment — the point where hard work, resilience, and passion converge into pure joy.

It’s the same feeling we aim to give every athlete who trains with us. Whether it’s finishing your first ultra or earning a podium in one of the world’s most iconic races, Arduua is both the challenge and the reward.

This story lives in our brand, our community, and our apparel — a constant reminder that the steepest climbs lead to the most meaningful victories.
