East Europe. I looked in the player program, there is Tour de Suisse/Switzerland but only for women. There is also Tour of Belgium/Slovenia next week. But no Tour of Suisse for men at all. Eurosport player is kinda geo-locked, sometimes even the prices are different. So the content can be different. I was hoping Eurosport UK will have it live, but from their schedule it doesn't look like it. Apparently in France might be ok if the tv schedules are correct but my French is dusted.
Where are you from?
In Germany Tour of Switzerland is shown on Eurosport Player only, as the TV-Channels show French open.
It's on Eurosport 1 in the Netherlands though.
It's neither on Sportklub or Arena Sport, so indeed a bit weird Eurosport doesn't have the streaming rights.
RTL.lu doesn't show Tour of Switzerland anymore. Back in the day their stream wouldn't even be go-restricted like with other races.
Maybe your lucky and Eurosport Russia shows it on one of their TV-Channels. In that case you're certainly going to find a stream on livetv.ru with acceptable image resolution.
Depending on whether you speak Russian, English or German there should be streams in decent quality.
The Russian language ones have good image resolution most times. If someone streams SRF, quality should be fine as well. British Eurosport might be bad though.
