ultra x world championships
The Ultra X World Championships is the pinnacle of multi-stage ultramarathon racing. In June 2021, the world’s greatest ultra runners will race over 5 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.

How To Qualify
Due to Covid-19, Ultra X have had to postpone or cancel a number of races this year. These races would have been used as qualifiers for the Ultra X World Championships. We have therefore taken the decision to alter our qualifying requirements for the 2021 World Championships only.
Instead of only accepting runners who have qualified through Ultra X races, we will be defining the elite level entry for the inaugural World Championships using the internationally recognised ITRA Performance Index. Anyone with a minimum ITRA Performance Index of 600 for Women and 725 for Men (as of 30th March 2020) will be permitted to enter.
To reiterate, there are six ways you can get to the start line;
Elite Entry: There are 100 places available for elite athletes with a minimum ITRA Performance Index of 600 for Women and 725 for Men (as of 30th March 2020).
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.
Ultra X Allegiant Scheme: Anyone that has completed two or more Ultra X events in the two years preceding the World Championships 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.
Invitation: There are 20 invitation places available to those who have not qualified by other means. These will be drawn at random from those that complete the application form. Each Saturday from 27th June we will hold a ballot to draw the winners.
Luck: Winning one of two free places in our launch competition (entries closed 26th June).
How To Apply
Applications to the Ultra X World Championships are open.
There are 150 places available for non-professional (age group) athletes. Those who have already qualified for the Ultra X World Championships 2021 will be officially notified on 23rd May 2020. Any places not claimed two weeks after applications open (11th July 2020) will be made available to general entrants.
All other places will be allocated on a first come first served basis.
Good luck!
