The route is challenging this year, with 4 mountain climbs. Fortunately it is not one of the longest, at 86 miles.


In round nubers:


Chaussey:           1000m of climbing

Croix de Fer:      1600m of climbing

Mollard:               around 300m of climbing

La Toussuire:      1100m of climbing


Apart from around 17.5 miles of undulating territory after Chaussey, the whole route is either climbing or descending!
