It's a shame how off topic this thread has become. Getting back on topic, as well as the classic climb up Alpe d'Huez, there are also a couple of other roads leading into town. The different options are documented on this post at cycling-challenge.com.

PS. Lance may not have officially confirmed his appearance at the Tour de Romandie, but it is highly likely that he'll be there since the Giro appears to be his main goal this year and the TdR is known as the perfect warm-up event. I don't expect him to be riding too aggressively there, but it's pretty certain that he'll be there. Plus, if he starts then I'm sure he'll finish (because that would be better for his training).
