Dolomiti Endurance

Your epic challenge between Gravel and Mountain Bike in the heart of the Dolomites

Born for riders who want more

Dolomiti Endurance is designed for those who seek more than a single gravel event or an MTB marathon.
It is a combined challenge uniting two worlds, two off-road souls, and two unique stages.

How to join the Combined Challenge

You can participate if you are already registered for one of the two races:
GT3 Lavaredo – UCI Gravel World Series
or Mythos, in its two versions:
UCI Mountain Bike Marathon World Championships and Mythos Primiero Dolomiti Marathon.

If you are not yet registered for either event, you can sign up for both and enjoy a discounted combined entry fee.

Two challenges. Two territories. One great achievement.

Auronzo di Cadore – GT3 Lavaredo UCI Gravel World Series

June 20, 2026

Ride at the foot of the Tre Cime di Lavaredo, surrounded by world-famous scenery.
Here, your gravel bike becomes your passport to European and World Championship qualification: speed, flow, focus.

Primiero – San Martino di Castrozza – Mythos Primiero Dolomiti

UCI Mountain Bike Marathon World Championships
September 11–12, 2026

Three months later, the mountains will demand more: technique, power, endurance.
This is the Marathon World Championship, on an iconic course that awards the rainbow jersey.

A format that puts you at the center

Dolomiti Endurance is more than a combined race.
It is a journey of growth, a story with you as the protagonist.
If you conquer the lightness of gravel and the toughness of marathon MTB, you will enter the Dolomiti Endurance special ranking.

Not just a title, but recognition for those who embody spirit, resilience, and versatility:
the true Dolomiti Endurer.

A double finish, a double reward

Complete both races and receive the exclusive Dolomiti Endurance recognition.
Not just a prize, but the symbol of a double achievement between Cadore and Primiero —
a seal celebrating resilience and the pride of riding in a UNESCO World Heritage landscape.

Who can join

All riders affiliated with FCI, UCI, and accredited cycling federations.
Non-licensed riders may participate with a valid medical sports certificate and the purchase of a one-day license.
