I wish I could also do this, after finishing my paragliding & ski experience, I think I can give it a try. This is an amazing to watch this, I’m amazed with the kind of determination these guys have. Same with the Tour de France, In the middle of peak summer these people cycle for close to 200 km in a day through all terrains in France. Read my previous post on my adventures in Chamonix. This is my 3rd visit to this place, u can read the previous post here.
