During that period, the club managed to finish third in the First Division twice, as the best result, before its relegation to second division. Lech managed to return to the first division in 1961, but after two seasons with poor results, the blue team was relegated again in 1963. The club even went down to the third division, then known as the Interprovincial Division (Liga międzywojewódzka), in one of the biggest sports crisis of the organization.
