We will progress between Chamonix and Courmayeur via the Bourg Saint Maurice. The different stages will allow you to get to know the whole route. Each evening you will rest in the comfortable accommodation.

During these 4 days we will run on average 25-40km a day. We will cover 145km in total, with 9100 meters of altitude gain. We will mainly be on single tracks and technical terrain. We will partially be on aerial paths.

Day 1: Courmayeur - Petit Saint Bernard pass

40km Meeting in **Chamonix** at 6AM – transfer to **Courmayeur** by taxi. The first day takes you to the **Val Veny** at the foot of **Italian Mont Blanc** towards the **Chavanne pass**. After a long path in balcony, a beautiful ascent awaits you before descending in the **Aosta valley** direction. Then begins the ascent to the **Petit Saint Bernard**, which marks the border between **France** **and Italy**. An area full of history. You enter in **Beaufortain**.

Day 2: Petit Saint Bernard pass - La Gittaz

40km The second day begins with a long descent to **Bourg Saint Maurice** through the pastures. Be careful with your feet because the rise to Fort de la Platte is tough! Then you will reach a wild and technical **Beaufortain** with the passage near **Forclaz lakes**. Then the **Passeur de Pralognan**. Here we must have a mountaineer foot. A long descent finally takes you to the **Cormet de Roselend** before the Sauce pass, the last difficulty of the day.

Day 3: Cormet - ND de la Gorge

44km For this step, you will discover the **Outray** mountain before descending to the valley and see the **Beaufort** and **Hauteluce** villages. The trail takes you to the **Joly pass**, the border between Savoie and Haute Savoie. It will then be time to descent to **Contamines** via the Roman road (runners of the legendary utltra trail around Mt Blanc will take this road in reverse).

Day 4: ND de la Gorge - Chamonix

26km Last stage of your journey, it is also the shortest for you to get in good shape in Chamonix! The route will lead you through the pastures at the foot of the **Mont Blanc glaciers**. You will appreciate the beauty of the **Truc and Tricot passes**. A final descent and you will only have to go between **Les** **Houches** and **Chamonix**!
