Haha, that is a-ways away. Scientists today do have hoverboard technology, but are afraid to release it to the public, and they would cost more than most could afford. They use prime materials from the earth, like ore, super-magnets (I'm not sure how they get it to hover magnetics or ???), etc., but anyways that won't be in my time or yours, or at least for quite some time.
I think they will probably start playing football on hovering pitches! and marathons will be on tracks that go in every direction and wind around and the people who run it have sucktion boots! Basketball would be zero gravity so that the people who play it would float around and it would be super easy to score in the net! That would be wicked!!!!
