Tim Tollefson in the Alps

4 - 12
One of the world’s great trail runners, Tim Tollefson, joins Run the Alps for a week of running around Chamonix and Mont Blanc. We’ll spend time with Tim in his favorite spots, including quiet and lesser-known trails.

Run the Alps is thrilled to be partnering with our friend and one of the world’s best-known trail runners, Tim Tollefson, for a unique and memorable trip!

Tim has spent plenty of time in Chamonix, especially on the UTMB Mont Blanc® route where he has achieved two third place finishes. Tim will share with our guests his favorite single-track trails, including some special, quieter trails. Along the way, we’ll have the chance to summit high ridges and run through quaint villages and beautiful Alpine pastures.

We’ll head into the Aiguilles Rouges mountains, high above Chamonix, taking in dramatic locations like the Aiguillette des Houches, and the Vallée du Berard with its beautiful waterfalls. Most of this area is a nature reserve, so we’re likely to see wildlife – as well as the striking views of the Mont Blanc range across the Chamonix valley. 

We’ll have one night in a high mountain hut, the Refuge Albert Premier, perched on the side of the Le Tour glacier. This will be an memorable experience, sleeping high in the alpine zone at 2,702 meters, or just under 9,000 feet.

During the week we’ll take the famed 11.6-kilometer long tunnel under Mont Blanc and spend one night in Italy, staying in the classic Aosta valley town of Courmayeur and running a section of the UTMB Mont Blanc course. Once there, we’ll take a time out at the Pré-St-Didier Roman-era thermal spa.

We’ll learn about all things Trail Running from Tim throughout our time with him. Watch this great film to learn more about Tim:
