With its 12 races of 20 to 180 km, the Ut4M offers tailor-made challenges. The Grenoble metropolis is yours through its 4 massifs: the Vercors, the wild Taillefer, Belledonne and its Alpine peaks and the legendary Chartreuse!

 

What you will find there:

• 12 races spread over 4 days which allow you to create 90 combinations;

• Two trails with a daily stage of 40 or 20 km, to discover a massif per day;

• Nature as you can't take it anymore and crazy landscapes that will make you forget the limits (or even ask for more);

• A feast of kilometers and elevation gain.

 

Course focus:

More like ultra-trail or a more moderate distance? In both cases, you'll be amazed: mountain ranges, snow-capped peaks, and breathtaking panoramas of Grenoble. On the program? Technical trails, steep ridges, and legendary spots like the famous Belledonne lakes or the mysterious forests of Vercors. The UT4M is much more than a race: it's a community of enthusiasts who support each other and push themselves to the limit. And with such views and a crazy atmosphere, even the spectators want more! Bonus? Once you've clocked up the miles, it's time to explore: the region's culture, history, and gastronomy are just waiting for you.

 

3 (very) good reasons to participate:

• Tailor-made challenges with 12 races from 20 to 180 km to be combined as you see fit (well, as your legs will allow);

• The incredible landscapes you'll cross. That's motivating 😏;

• There you'll really have good reasons to show off at work!
