The club won their first championship in 1974, beating Říčany 15-0 in the final.

This turned out to be the start of a phenomenally successful era for the club, which saw them winning the next seven championship titles.

Jan Navrátil,[1] former international prop and their coach at the time, rescued two men rendered unconscious from a resulting gas leak, while trying to repair some freezing equipment in the cellar of the clubhouse.

Navrátil subsequently died from gas poisoning and was posthumously awarded a Fair Play Award by the Czech Olympic Committee.

The club also named their home ground in his memory.
