Ultra X World Championships












1-8 JUN 2024

ultra x world championships

The Ultra X World Championships is the pinnacle of multi-stage ultramarathon racing. In June 2024, the world’s greatest ultra runners will race over five days and 250km to become the undisputed multi-day ultra King or Queen.

The course is located in western Slovenia, nestled between the towering Julian Alps to the north and the Adriatic coast to the south. Competitors travel north from the vine-laden landscapes and high plateaus of Vipava Valley to the emerald green waters and rocky mountain trails of Soca Valley and the southern Julian Alps.

The full 2024 event information pack will be released in January 2023. The format will be for the most part the same as 2022 and the course will remain unchanged. 

Find out how to qualify below.

How To Qualify

To qualify for the 2024 World Championships you will need 10 points gained from Ultra X races between January 2022 and May 2024.

5 stage race = 5 points

2 stage race = 3 points

100km race = 2 points

50km race = 1 point

No points are awarded for non ultra-distance races. E.g Spring Trail Series Half Marathon event.

A podium finish within an age category = points multiplier x 3. E.G If you come 2nd in your age category at Ultra X 125 Azores you will have earned 9 points (3 points x 3). This will leave you 1 point short of WC qualification.

Black ribbon finishers = points multiplier x 3 (this cannot be used in conjunction with a podium finish).

Green ribbon finishers = points multiplier *2 (this cannot be used in conjunction with a podium finish)

Every World Championship cycle you will lose 50% of your points.

First placed competitors within their category will have 30 days to enter the World Championships after their race. If not claimed within the 30 days, the place will roll down until it is claimed. 

Other ways to qualify:

Elite Entry: There are 100 places available for elite athletes with a minimum ITRA Performance Index of 600 for Women and 725 for Men

Qualifying at Ultra X Races: Anyone that has qualified for the World Championships through exceptional performance at other Ultra X races is eligible for entry.

Charity Places: There are 20 charity places available to those who commit to raise funds for a registered charity. Places will be allocated on a first come first serve basis. There is no minimum figure to be raised.
