A new program in Challenge events, or better yet, Extreme events, this is the first year for the event and will take place in May. The organization behind is well know, ASO, the same organization that runs the Tour de France, Paris Marathon, and many others.

This unique event offers an 'a la carte' composition of trail runs and mountain bike rides over 4 days. Several thousand people are expected this year according to the site. This might be a perfect way to tie in a road riding trip to France and do it all in 10 days! 2010!
