Yes, it is actually okay. But one of the most common problems with a free VPN is that there are only small server networks. This in turn will result in overcrowded and at the same time slow servers.
In addition to that, there is a limited IP address which you can choose from. In other words, you will have a difficult time unblocking the Nascar.
If you want to have a fun experience, we highly recommend that you use a trusted and premium VPN that has a money-back guarantee like ExpressVPN that will allow you to use the service for free.
