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, 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 team of highly qualified coaches. 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, personalized coaching in both Spanish and English.

Beyond coaching, we’ve developed the Arduua Trail Apparel brand — meticulously crafted for trail runners by trail runners. Each garment blends high-performance, breathable, and lightweight materials with distinctive design and unmatched functionality, tailored for the demands of the mountains.

Our signature pieces — including trail running skirts and shorts — showcase the perfect fusion of technical innovation, comfort, and Arduua’s unique style, inspired by Spain’s rich trail running culture.

Arduua – The Story of a Name

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

Ardua = Steep (Latin)
Arduus = Steep, demanding, unattainable
Arduous = Hard to achieve
Arduua = The profound joy when you achieve your goal

At Arduua, this name symbolizes more than just the physical ascent — it represents the emotional and mental journey of every runner: the discipline of training, the courage to start, the grit to persevere when it’s tough, and the pure joy of reaching the summit.

That’s your Arduua moment — where hard work, resilience, and passion converge into transformation.

Whether it’s finishing your first ultra or reaching the podium of a world-class race, Arduua is both the challenge and the reward.

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