La Trott'aux Fous

New for 2026: The Valais Terroir Marathon goes nighttime!

Get ready for a 5K run like no other in the heart of Martigny. Designed with fun in mind, La Trott’aux Fous immerses you in a festive and quirky atmosphere.

The 5K race starts at 9 p.m.

Along the route, two aid stations have been specially designed as mini rave parties, complete with DJs, lights, and local delicacies to enjoy. With surprises, a festive atmosphere, and a wild section, everything comes together for a unique experience to share with friends.
And once you cross the finish line, there’s no need to wait: we’ll jump right into Maratho’Night starting at 10 p.m. to keep the party going all night long.
And to top it all off, a costume contest will reward the most creative participants.
With 1.5 hours to finish, everyone can enjoy the event at their own pace… even if it’s just walking!
