Mad, painful, exhilarating and fun. Did the 4 man bobsleigh back in 2011. 3 passengers and a professional driver. It was expensive and over in a minute, but one of the best experiences of my life.
The sort of thing you will probably do only once, so if you're in La Plagne and you have the opportunity, just do it. I still get a buzz from watching the pro's doing it on TV and telling my wife 'I did that once'. Think she's sick of me now - and the 2014 Olympics is just about to start!
