I don't recall the ability showing which version you have though the legacy options to buy faster speed will show you when you are up to that speed. Talk to your class trainer to see what general abilities you can still get - if it shows speed 2 or speed 3 then you don't have those yet. For a subscriber ignoring the legacy benefits you get speed one at level 10 and i think tow at level 25 and three at level 35. That is the highest without a legacy purchase, as the post above pointed out.
