For the most of Europe coverage will be supplied by Eurosport (Normal and HD).

For the US or Aus or anywhere that doesn't have Eurosport there is also the option to
watch it live over the Internet for €4.90, not a bad price for the coverage that you get.

They also have video-on-demand in-case you missed anything.
