Velocity is a vector. It is a combination of both speed and direction. In order to travel around an oval track (or a circular track, for that matter), you must change direction.

Changing direction changes one of the parameters of velocity. At that point, your velocity is no longer constant.

Because velocity is a vector quantity.
If you change direction, even if your speed is the same, you are changing the velocity.
