The 2008 Tour de Romandie route is also available on their website and runs from April 29th to May 4th. The vague map on that page isn't overly informative, but the pdf linked to from it suggests that its going to be a very mountainous route this year.

It's normally a pretty good race that a lot of top riders use as training for the big three-week tours. In 2006, we watched the main mountain stage of the race, which finished in the ski town of Leysin. A rider I'd never heard of before sprinted away from everyone else halfway up the climb to take the stage - his name was Alberto Contador. In the final time trial around Lausanne, he lost a bunch of time to Cadel Evans, who won the TT and took the overall lead. We posted some photos from both of those stages on our photo-blog here. The end of the 2007 Tour de France was extremely similar, with the same two riders involved, but by then Contador had improved his time-trialing enough to hold onto the overall lead.

We'll probably try to get to at least one of the two stages on the weekend:
Saturday, May 4th is from Sion to Zinal (at the top of a side valley in the Valais), 127km with 3,500m of climbing.
Sunday, May 5th is from Le Bouveret (near Montreux) to Lausanne. Those towns are only about 40km apart, but the route is 159km with 1,800 metres of climbing, so they must be going over one of the passes in the Vaudoise Alps.
