Hopefully you get some feedback before registration closes..
But if not you should do the race anyway and then write about it here for the next guy who wants to know. You could be the leader instead of the follower. And maybe even the race leader if you've done all your training homework /img/vbsmilies/smilies/wink.gif
What's to say about other than it replicates a climbing stage from the TdF of the given year the Etape your interested in takes place. In other words, the 2012 Etape will use the same route as one of the climbing stages of the 2012 TdF. As such, the Etape is not the same every year. There are loads of riders, some ex-pros and some of those ex-ProTour riders. Here's the link for this year's Etape: http://www.letapedutour.com/ET1/us/20111011-2012-etape-du-tour.html . Since the TdF stages and routes haven't been named yet, the route for the Etape isn't known yet. No matter the route, I've yet to hear of anyone not enjoying the hell out of it.
