This is an alpine sportive that climbs Col du Glandon, Col du Telegraphe, Col du Galibier and L'Alpe d'Huez. There is also the Ultrafondo, which starts at 5am and tackles Alpe d'Huez twice - totalling 226km with over 10000m of climbing; for more information on this, see the Marmotte Granfondo Alpes website.
I've added the official ultrafondo route to routes.fun, along with waypoints and the invaluable route card creator. Ultrafondo Marmotte Alpes on cycling.routes.fun
