UT4M: Grenoble’s Ultra a great success!
An ambitious but successful wager for this first edition of the Ultra Tour des 4 Massifs. The UT4M started on August 23, 2013, in Paul Mistral Park, located in the heart of the city of Grenoble (France). This event stands out from other trail ultras by linking together the 4 mountain ranges that surround the capital of the Alps, without ever losing sight of the city. Three courses, 4 climbs to an altitude of almost 2400 meters, 10,000 meters of vertical gain, and more than 950 participants for this first edition! Petzl would like to express its gratitude to both the participants and organizers of the UT4M…
