Racing with Purpose.
Protecting What We Love.
At One Hundred® Sports Group, true endurance means more than reaching the finish line. It’s about protecting the landscapes that make trail running extraordinary.
We embed sustainability into every event, ensuring that the trails we run today remain alive for generations to come.
For every athlete who races with us, a tree is planted in partnership with Evertreen , helping to restore forests and ecosystems most affected by deforestation.
Each tree absorbs carbon, protects biodiversity, and stabilises soil, creating tangible impact far beyond race day.
But our commitment goes further. Guided by our principle of “Leave the mountain better than we found it,” we actively reduce waste, limit environmental footprint, and inspire a culture of care across our global endurance community.
From eco-friendly course design and recyclable race materials to carbon-offset initiatives and community education, we are redefining what responsible trail running looks like.
When you join a One Hundred® event, you’re not just testing your limits, you’re contributing to a global movement that uses sport as a force for environmental good.
Run hard. Tread lightly. Race with purpose.
