 For the next decade Olímpic was a dominant force in the third level, successively finishing in the top five and reaching the Segunda División promotion play-offs three times, being ousted by Gimnàstic de Tarragona in 1959, CD Málaga in 1960 and CD Atlético Baleares in 1961.These disappointments led to a slow descent which culminated in relegation to the regional championships, following the restructuring of the divisions in 1968.Olímpic returned to the third division – renamed Segunda División B – in 1977, finishing in eighth position in its debut season but bottom of the charts in the following campaign, eventually slipping back to "Preferente" in 1982.
