Shifting

I have a problem with my car. I have been having a hard time shifting into third and fifth. When i am racing i go to shift into third and you can feel it go in but when you let out the clutch it isn't there.. It just revs up. If i push in clutch again then it goes in. If it is in normal driving it goes in good. THe ohter night i was racing and i shifted ito fourth hard then after that i can't seem to get it into 1, 3 ,5. DO you Guys think my cable migh tbe junk. It's the only thing i can think of unless my clutch master cylinder is bad?

It is a 93 prelude 2.2 vtec
