Located between Granada and Seville, the Campillos circuit was chosen as the setting for the 2021 FIA Karting World Championship - OK & Junior partly because of its very southern location in Europe. Further south than La Conca (ITA), less open to oceanic influences than Portimão (PRT), it should be able to offer good weather conditions from 28th to 31st October for the big end-of-season event.

The fourth event of the FIA Karting European Championship - OK & Junior started in the centre of Spain at the Circuito Internacional de Zuera in very hot weather. On Friday 23th July, 139 participants took part in the qualifying practice for the latest European competition, 56 in OK and 83 in OK-Junior, in temperatures ranging from 35 to 39°.
