Milly Young, a 34-year-old Australian endurance athlete, recently made history by becoming the second woman ever to finish in the top three of the PTL (La Petite Trotte à Léon) during UTMB. Known for her adventurous spirit, Milly’s journey through this grueling 330-kilometer race around Mont Blanc tested her mountaineering skills, self-reliance, and team dynamics alongside her brother, Charlie. Her passion for technical challenges and exploration made the PTL a natural fit for her, and her remarkable performance solidified her as a trailblazer for women in ultra-endurance sports.

The Marathon du Mont Blanc weekend has just wrapped up, and as we shake off the feeling of the past few days, we can't help but marvel at the experience. It was a privilege to be there, immersed in the vibrant energy of the community, watching people come together to do what they love most—running and cheering along the scenic trails.

Summer has arrived in the valley, bringing the excitement of running season. As runners from around the world gather in Chamonix, we often hear people say, "I could never do that," or, "I'm good on the road, but I can't run trails." If that sounds like you, don't worry—we believe anyone can enjoy trail running. We've compiled a list of ten trails to inspire you, perfect for all levels. Whether you're transitioning from road running or looking to explore new routes, these trails will help you discover your potential and the beauty of Chamonix.

Trail running in Chamonix is a bucket list adventure. But how does one navigate the trails, or transition from road running to the rugged terrain around the Mont Blanc? How do we fuel for long days out? Luckily, this camp covers all the topics. It’s a guided, worry-free gateway into the trail running community.

What is trail running? 

According to Wikipedia, 'Trail Running' is a sport-activity which combines running, and, where there are steep gradients, hiking, that is run "on any unpaved surface".  Anyone can trail run, whether this be competitively or just getting out and enjoying the nature.  Here we highlight the key kit you need to get started.

Trail running is great because you don’t need very much to start, a lot of us think we need more than we do. The key is to make sure your gear is safe, useful and light weight.

Ideally you want the minimum gear to travel quickly and as comfortably as possible. But things can change quickly on the trail, such as weather and injury, so you might find yourself taking more than you use. If you’re unsure, try checking local races for mandatory kit checklists and you can often base what you pack accordingly.
