I particularly enjoy watching highlights of the Tour and the Vuelta, but have always struggled with obtaining Giro coverage. I think the Giro is in many ways the best of the three Grand Tours and is especially interesting this year as Thomas looks like he's a realistic contender. Anyway, I've paid for Eurosport in the past but always found that anything other than live coverage was pretty useless.
Highlights are being screened on Quest at 10pm each day but it's only available on Freeview. We only get Freesat so I though I was stuffed. But I just found I can watch all Freeview Channels live on a site
http://www.tvcatchup.com/ including Quest. I just tried it and it seems fine. Looking forward to 10pm and Thomas's assault on Etna.
Hope this is useful to somebody.
