One of the biggest sportives in the work attracting over 7000 competitors a year. The event starts in the centre of Bourg d'Oisans before tackling the Col de la Croix de Fer, Col du Telegraphe, Col du Galibier before finally finishing at the top of Alpe d'Huez after 174km and over 5000 metres of climbing.

To compete in this event you need to have put a serious amount of training in and be ready to enter in October the year before.  If you are thinking of competing in this event them it may well be worth travelling to the area the year before so you can see what you are going to let yourself in for !

As official partners to La Marmotte we have a selection of guaranteed entries each year for the event.
