Claude and Sébastien are two friends from Lyon (France). Last year, Seb left for a long cycling journey to ride the Silk Road from Lyon to Beijin (see his website Lyon-Pékin). To sum up his journey, he cycled 12 000 km in seven months! And Claude joined him for a part in Iran. Stop wondering where the idea of the Geotrail comes from ;). Bot of them were the first readers of the proposal of the Geotrail. Seb shared his large experience with us, and we learnt so many important details that will make our everyday life during our expedition.
