The main difference lies in eligibility and the opportunity to compete for the title. The World Championship races are exclusive to participants who have qualified by winning a slot at an XTERRA event. These participants compete for the chance to become World Champion. In contrast, the Open category allows anyone to race on the same course as the World Championship, but without the opportunity to win the World Champion title, prize money, or attend the awards function.
Only those who have qualified by winning a slot at an XTERRA event are eligible to participate in the World Championship races.
To qualify for the World Championship races, you must compete in an XTERRA event and win a slot that grants you the opportunity to compete for the World Champion title. For more information on how to qualify, click here.
If you feel that you should have qualified for the 2025 XTERRA Trail Run World Championship but haven't received your official invitation, please email trailrun@xterraplanet.com before May 10, 2025.
The Open category is open to anyone who wishes to race on the same course as the World Championship participants. No prior qualification is required.
Entrants into the World Championship receive World Championship Swag and memorabilia, Invitations to World Championship Celebratory functions and eligibility to World Championship titles and prize money
No, participants in the Open category will receive different finishing medals and gear, distinguishing them from those competing in the World Championship races.

For the World Championship Races:

Medical exceptions will be considered, but not guaranteed. Email a written request with your name, event name, and reason for the request accompanied by a valid medical certificate. Active Refund is highly recommended and available for purchase during checkout.
For the Open Races:
Option 1: Transfer to another competitor
You may transfer or sell your place to another person wishing to take part in the event. This can be done free of charge, at least ONE calendar month prior to the event via your Etchrock account, details of which can be found on your entry confirmation email.
If there is less than 30 days before the event, transfers to another competitor must be made at registration at the event and will occur a £10 admin fee. Only the participating athlete needs to attend registration to complete the transfer.
Transfers between athletes must be completed through the correct channel so that we have the correct participant information and contact details in the event of an accident. DO NOT give your bib to someone without completing an official transfer. Running on another athlete’s bib contradicts NGB rules and will result in disqualification.
Option 2: Ticket Deferral
If there is at least one calendar month before the event you can defer your entry and receive credit to your Etchrock booking system account for the amount paid, minus a £10 admin fee.
You can use this credit to enter the same event the following year or any event that comes before it.
A ticket cannot be deferred more than once.
Deferrals may be used against entries of a higher value, on payment of the difference.
Deferrals can only be used against a single transaction and cannot be exchanged for cash. No change or refund will be given.
The following links provide instructions on using your Etchrock account to carry out the desired actions.

All competitors must carry compulsory kit. The lists can be found on the page for the specific race distance. This kit is for your safety due to the often unpredictable and quickly changing mountain conditions and isolated nature of the route. Spot checks will be in place and anybody found without the required kit will not be allowed to race.
The minimum age may vary for each race distance due to the National Governing Body guidelines. Please select the distance from the event page to find specific Minimum Age requirements along with other race information.

We are always looking for people to join our amazing team of event volunteers and marshals.
Marshalling can be a great way to get involved, enjoy the atmosphere and spend time with friends, as well as meeting new ones. Time after time our athletes tell us it's the marshals' support and enthusiasm that makes the event for them - we are known to have the BEST event marshals in the world!
From feed stations to directing runners, managing transition, tail ending or giving out medals on the finish line we will help find a job that suits you and welcome anyone of any age and even dogs (in certain positions). Many clubs and community groups join in and tell us it's a great team bonding experience as well as a lot of learning for younger members and a great way to raise funds for their club or group.
To show our gratitude for what our volunteers bring we have a great reward scheme in place.
If this is something that would interest you drop us an email at marshals@alwaysaimhighevents.com
