The first edition of the "Roll'Athlon 100" took place in early June through three departments crossed by the Rhone river (France). Rollerskis and roller-skaters participated in a 103 km race between water and mountains. Maybe some of you have known the famous Swiss race, the "One Eleven". The concept is quite the same! Back on the organization of this event with Gael Jacob and Benoit Gamba...
