I really enjoyed it. I thought some of the race footage was great, especially on the big screen. Loved the shots in the mountains, and the footage of the descents. Some real LOL moments too ... Mark Renshaw aka Prince Harry was one. I also enjoyed the Q&A session - it made you feel part of a unique event, although I would like to have seen more questions from the audience. Cav may be awkward and inarticulate, but he wears his heart on his sleeve, and is much more honest and open than most top sportsmen (no Tiger Woods style "It is what it is" replies).
If I'm being critical, I thought they should have shown a bit more footage of the race that wasn't centred on HTC-Columbia's performance - Contador hardly got a mention and he won it! They could have made a bit more of the fact it was Lance's comback and the friction between Lance and Contador.
