CARBON MITIGATION PLAN

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!

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.

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!

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.
