I have a WatchAFL subscription through my Crows membership, so I don't need Kayo to watch the AFL. If Kayo doesn't have Eurosport, and only show the same races as SBS, then there's no point in me subscribing to Kayo.I can't see how they could show it to be honest, they don't include Eurosport in the subscription so I am assuming they will not show it. I might tweet them and see what they say, but I have also been trying to work out how to watch Eurosport in the meantime, which is a massive PITA!
I do know of a site which streams cycling races, in reasonable quality. The legality of said site is dubious at best, so I won't be linking to it here on BF.
