Yeah, it was very frustrating, and after all, 10 km had to suffice, plus short videos of previous most interesting moments from Steephill, although Steephill site is not entirely spoiler-free. Thanks anyway!
Request for the wonderful forum members of Cyclingnews: could you guys please post spoiler-free last x km (as many as possible, especially for interesting stages) every day here. It can be sourced from Steephill. During weekdays I might not be able to visit Steephill every day (much less watch the Giro live) and Steephill spoils the results after a day so I am looking for a reliable way to watch the stages as if live.
You can find full coverage of all stages legally on Rai (no matter your ip), but the stage winner's name will be next to the stage number...
Here's where the spoiler is:
If you are prepared to put one of your hands on the screen so you can't see it, and then scroll down 'till it's no longer a problem, it's pretty safe (except for the tab name which also has the spoiler).
Just note that you might be unable to watch the most recent stage immediately. I can watch the first three stages without any problem, but the player won't start with the stage today. It was the same yesterday for me, so later today or tomorrow today's stage should be fully working.
edit: As predicted the stage 4 link works perfectly now. However for some reason it doesn't contain the first 40km
