HOKA Val d’Aran by UTMB® strengthens its commitment to sustainability and reducing its carbon footprint.

Our love for the trails and the natural ecosystems goes hand in hand with our responsibility to protect them. That’s why the HOKA Val d’Aran by UTMB® has taken a significant sustainability step by implementing concrete actions to mitigate its carbon impact. The approach is built on two main pillars: reducing the operational footprint and contributing to high-environmental value projects. Join us in this shared effort to run for a healthier planet!

HOKA Val d’Aran by UTMB® strengthens its commitment to sustainability and reducing its carbon footprint.

Los senderos y ecosistemas naturales que nos rodean merecen ser preservados, y en HOKA Val d’Aran by UTMB® asumimos el compromiso de cuidarlos. Por ello, hemos dado un paso decisivo en sostenibilidad, implementando medidas concretas para reducir nuestro impacto de carbono. Este compromiso se articula en torno a dos pilares fundamentales: disminuir la huella operativa del evento y apoyar proyectos de gran valor ambiental.

MINIMIZING THE CARBON FOOTPRINT

At HOKA Val d’Aran by UTMB®, we are committed to sustainability and to reducing our carbon footprint. That’s why, back in 2023, we designed a collective mobility plan to make transportation across the Val d’Aran easier and more sustainable.

Thanks to this collective transport plan, in 2025 we significantly reduced the event’s carbon footprint:

20 buses in operation
Up to 2,400 fewer cars on the roads
8,800 people transported (runners and companions)
5,1 tonnes of CO₂e emissions avoided

In 2026, we will strengthen these measures even further, reducing the use of private cars and promoting collective transport.

Your trip can also leave a positive footprint

This edition we’ve added a new feature to the registration platform: the option to voluntarily calculate and help offset the carbon footprint of your trip to Vielha. You choose:

1- Calculate the CO2 emissions of your journey

2- Decide if you’d like to voluntarily support projects that reduce and/or avoid the same amount of emissions as those generated by your journey

3- Add the carbon contribution to your registration with a single click

4- Nature thanks you!

How does the carbon contribution work?

Your contribution finances certified projects, validated by Spain’s Ministry for Ecological Transition and Demographic Challenge (MITECO), ensuring that 100% of the funds go to high-impact initiatives.

• Some projects will have a local impact in the regions hosting HOKA Val d’Aran by UTMB®.

• All comply with the most demanding international certifications.

• The cost is calculated according to your means of transport, distance, and is set at €25 per tonne of CO₂e.

Approximate round-trip examples:

• Spain: between <€1 and €10

• France, Italy, England: up to €20

• America: between €45 and €85

• Asia and Oceania: between €65 and €130

With these initiatives, at HOKA Val d’Aran by UTMB® we continue moving towards a more responsible, sustainable, and environmentally respectful event model.
