Today’s challenge was the Col du Galibier, 2700 m above sea level. The day was not arduous however — there were plenty of opportunities to explore, and to stop at alpine hotels and cafes. At the Col du Lautaret (an offshoot of the Col du Galibier), the University of Grenoble has a very fine alpine botanic garden, which is just off our route. At the Lautaret, the road forks and we turned right. However, some of us had the crazy idea to cycle the 55 km to the top of the most well-known of all TDF climbs: the ascent to the Alpe d’Huez (@90 km).
