help with ovid

First sentence ovid’s adaptation trying to work through it help my grammer.

Forsitan audieris aliquam certamine cursus veloces superasse viros.

I tanslated it

Perhaps you will be told some girl in a contest runing swiftly overcame the men.

I think that’s right but I need a definition of superasse

superasse=superavisse

You should also make sure that you take cursus as a Genitive.
