The BMW HERO Südtirol Dolomites is the toughest mountain bike marathon in the world. The constant commitment to real sustainability, ever since the first edition, has now taken shape thanks to the project FROM HERO TO ZERO: the sustainability manifesto adopts 16 concrete actions in the fields of environmental and social protection and governance. The actions are inspired by the 17 United Nations Sustainability Goals (SDGs) and by the sustainability guidelines issued by the UCI, the International Cycling Union, which has decided to present as the only Italian ‘best practice’ in the organization of sports events at the COP27 (Conference of the Parties) with the aim of sharing equality among all the countries of the world the responsibilities for tackling climate change in all its aspects.
