I guess if We take into account his personality which is often portrayed in comics as not exploiting his full potential, then We might as well just say, this is a comic book fight.
The faster character will have to slow down in order to present a decent fight because that is how he has been portrayed over the years.
In the particular case of Gladiator who is a warrior, I don't see how his personality will prevent him to use his power at full potential in a warrior vs warrior match, but since comics often slow down speedsters to make comics longer than a single page. Not using their full speed becomes part of their modus operandi. So no matter how much potential they have to use their speed they will not use it, because they simple don't show it in comics.
Since Glads is fighting with handicap and He has always lost with this handicap Thor wins.
But by numbers and potential Glads should win more often than not.
