The most accessible format
Perfect for outdoor enthusiasts looking for a first trail running experience or for trail runners who want to challenge themselves or train on short distances.
The challenging adventure
Fans of medium distances ranging between 50 and 100 km-effort, the 50K category is for you! The Finals of the 50K category will be held each year at the OCC race of UTMB® Mont-Blanc.
The pathway to ultra endurance
A unique way to test yourself over 100 km-effort and experience a full day on the trails, with the epic CCC® race of UTMB® Mont-Blanc becoming the Finals of the 100K category.
The mythical distance
Push your limits and achieve the ultimate trail running dream of completing a race of over 170 km-effort. The pinnacle UTMB® race of UTMB® Mont-Blanc becomes the Finals of the 100M category.
The 4 race categories are based on the km-effort, a globally recognized formula for measuring the race distance in trail running by considering both the distance and elevation gain to calculate the perceived distance.
The km-effort is calculated by adding 1km to the race distance for every 100 meters of elevation gain.
For example, a race of 50km and 2,500 meters of elevation gain has 75 km-effort.
Collecting Running Stones is the only way to access the UTMB® World Series Finals for regular runners.
What is a Running Stone?
A Running Stone is an entry into the lottery to participate in the UTMB® World Series Finals: the UTMB®, CCC® and OCC races of the UTMB® Mont-Blanc.
Only 1 Running Stone acquired in the past two years is mandatory to enter the lottery. Running Stones are cumulative, have no expiration date, and each Running Stone gives you an additional chance to be drawn.
How do I earn Running Stones?
You can only collect Running Stones by finishing races in the 20K, 50K, 100K or 100M category at a UTMB® World Series Event or UTMB® World Series Major.
Discover the 25 events that will allow you to collect Running Stones in 2022 to enter the UTMB® Mont-Blanc lottery from 2023 onwards.
Only accessible on this website, the UTMB® Index provides the performance level of each runner.
What is the UTMB® Index?
Assessing the performance level of each trail runner, the UTMB® Index is calculated for each of the 4 UTMB® World Series race categories: 20K,50K,100k and 100M. Trail runners are also given a General UTMB® Index calculated by combining results from all race categories.
A valid UTMB® Index is mandatory to enter the UTMB® Mont-Blanc lottery.
How do I get a valid UTMB® Index?
A valid UTMB® Index is achieved by completing at least one race of the UTMB® World Series or a UTMB® World Series Qualifier in the relevant category within the previous 24 months. Once a race category has at least 1 valid result, all races from the past 36 months will be used to calculate your UTMB® Index.
To enter the UTMB® Mont-Blanc lottery for the race of your choice, you must have a valid UTMB® Index as per the chart.
Under the new sports system, elite runners must qualify for the UTMB® World Series Finals.
Qualification for elite runners
To gain access to the UTMB® World Series Finals, the best athletes on the planet must qualify by taking part in the UTMB® World Series Majors or UTMB® World Series Events races over a period of 15 months. This allows elite runners to optimize their season and their recovery periods.
The first 10 men and women on the UTMB® World Series Majors, as well as the first 3 men and women on the UTMB® World Series Events in each of the 50K, 100K and 100M categories, will win a place at the UTMB® World Series Finals in the equivalent category.
