TDF coverage is the time-honoured 7pm-8pm highlights spot, combined with weekend live coverage. If you've got Sky or Virgin cable you can click through to live coverage using the red button.

After the highlights program on the opening day they showed a documentary about a British competitor in the Race accross America, followed by The Science of Larnce Armstrong the other night and Chris Boardman's 'The Hour' coming an a week or so. A year's worth of normal terrestial TV cycling coverage in a month..
