The climate crisis is leaving its mark on every corner of the planet. Changes in our environment threaten nature and put the future of coming generations at risk. In this context, major sporting events have an undeniable responsibility to take an active role in protecting our environment.
The Behobia - San Sebastián is not just a race; it is a celebration of sport, our city, and our firm commitment to the planet. Proving that it is possible to organize the ultimate sporting celebration while taking care of our land is not just a matter of transparency—it is the legacy we want to leave behind.
Our Journey: Every Step Counts


For years, Behobia has been strongly committed to sustainability. Aligned with the Sustainable Development Goals (SDGs) of the 2030 Agenda, each edition we work to minimize our impact through tangible actions:
- Responsible Waste Management: Deployment of infrastructure for proper waste separation and recycling along the entire route.
- Reduction of Plastic Use: Drastic minimization of single-use packaging at refreshment stations.
- Circular Economy: Encouraging the reuse of event infrastructure and organizational materials, alongside collecting athletic clothing to give it a second life.
- Sustainable Mobility: Active promotion of public transportation for participants and spectators.
A Continuous Commitment: Measuring and Improving Our Impact
We know that to move forward, we must understand the exact reality of our impact and maintain our efforts over time.
Following the major milestone of measuring our carbon footprint last year, we are renewing and consolidating our commitment for 2026.
To achieve this, we continue to count on GO2 by Global Omnium as our GREEN SPONSOR. This continuity is key for the organization: it allows us to compare historical data, evaluate the success of implemented measures, and guarantee real environmental improvement year after year. Their technical expertise supports us throughout the entire climate management process:

- International Rigor: GO2 by Global Omnium precisely calculates our carbon footprint according to the most demanding international standards (ISO 14064-1), providing reliable data to design effective action plans.
- Independent Certification: Because progress only happens through constant measurement, verification, and certification, our impact is validated by the prestigious certification body Bureau Veritas.
Running the Behobia is about pushing your limits. Doing so while caring for our environment, year after year, is overcoming the greatest challenge we face as a society.
