Enztal Cup (Puchar Enztalentu - Puchar Doliny Enz?) - Cup is 'Puchar' in Polish, so it should be translated. Let's go with 'Puchar Enz' as 'Enz' is a river name so it stays as-is. 'Tal' means valley, so 'Dolina Enz' would be the translation for the river valley name itself. Let's assume 'Enztal' is a proper name for the region like 'Tale of Enz'. So 'Puchar Doliny Enz' is a good fit.
