For those that don't have a tv package that gives access to any speedway the Discovery + deal is quite good IMO. Currently it's a rolling one month contract at ยฃ6.95 so it can be cancelled at any time . If purchased for the duration of the speedway season it would cost approx ยฃ50, as cheap as attending a couple of meetings . The app is readily available , most Samsung tv's up to 8yrs of age have it installed I believe plus several other devices ,alternatively a streaming stick can be used.For that price all the GP's, SON etc are covered as are all the british speedway meetings provided on Eurosport. Also there is much more than the speedway to watch on the app for those that don't have paid for tv packages.
I do have a tv package myself but have decided to subscribe to Discovery as I hate the unreliability of the Eurosport Channel when it comes to showing the speedway, although I can see where Discovery are going by only showing the SON on the app, presently it's a cheap watch.It will be interesting to see what happens to the costs when Eurosport disappears in the none too distant future
