I am travelling to Central Europe late sept early October. Over some free days I plan to ride some of the famous climbs of the TDF epecially interested in the Alpe D'Huez. Can anyone provide some information regarding how late in the season snow comes and closes the routes? I may be in the French Alps as late as the middle of October. Also if anyone can provide info regarding bike rental in the Huez ares (borg d'ossians?) I read that bike shops close at the end of sept. ANY info is greatly appreciated.
