Ut4M and its 12 races, from 20 to 180 km, offers all runners, from beginners to elite, the chance to set themselves their own challenge. A rather unusual tour of the Grenoble metropolitan area through our 4 mountain ranges!
What makes Ut4M unique?
- A route that crosses the 4 massifs surrounding Grenoble - Vercors, Taillefer, Belledonne and Chartreuse - projecting runners into 4 different worlds in terms of terrain, weather conditions and panoramas.
- The Challenge 160 or 80 formulas, two races with a daily stage of 40 or 20 km, which allow you to discover one massif per day and enjoy a rest or farniente time with family or friends.
- 12 races spread over 4 days, allowing you to put together a variety of combinations.
And once again, after last year's great success, we're offering the Rando Ut4M, which lets you experience the ultra atmosphere at your own pace! Hiking friends, you're welcome!
