Priority Registration is a 48-hour window of time immediately before general registration opens, where exclusive groups are invited to register early. The benefits of early registration are:

• first opportunity to secure a spot in the race and therefore greatest likelihood of getting a place in the desired race

• in some cases, access to the lowest price tiers

A limited number of race entries are available during the priority registration period, with a portion of entries reserved for general opening (for all UTMB World Series non-lottery events). This means priority registrations may sell out during the priority registration window, so it is first come first served! If the priority allocation sells out, please try again during general registration opening.

Runners holding a valid UTMB Index will be offered access to registration during the priority registration period.

The priority registration window is open for 48 hours before general registration opening. Please note that priority registration places are limited, so they may sell out during the priority registration window! If the priority allocation sells out, please try again during general registration opening (for all UTMB World Series non-lottery events).

The UTMB index is a formula developed by the UTMB World Series designed to assess the performance level of trail runners globally, based on their results from taking part in UTMB World Series events and UTMB Index races. View it here: UTMB Index.

• In most cases, simply holding a valid UTMB Index is sufficient to gain you priority access. However, if your race has a safety requirement, you must have a UTMB Index for that respective distance, or a greater distance.

• In your My UTMB account or on your My UTMB Index public listing, you will see a table under the heading UTMB Index which lists the different distance categories of 20K, 50K, 100K and 100M.

• If you have a valid UTMB Index, a number will appear under the UTMB Index. A number under any of the specific distances shows you have a valid Index for that distance.

There are two main reasons why your results may not show:

1. Your race is not a UTMB World Series Event and/or UTMB Index race. Please check the race calendar to see if it is registered as a UTMB Index race. If the race does not feature in the list then you will need to contact the race organiser and ask them to register as a UTMB Index race. This is free for event organizers to do and only takes a few minutes on utmb.world.

2. If the race is a UTMB World Series Event and/or UTMB Index race but no results are published,it is because we have not yet received the results from the race organizer. We will publish the results as soon as we receive them.

3. There might be a different spelling that prevents the system to attach your result to your profile. Use the tool ‘Claim your results’ to have your UTMB Index updated. We are checking the requests daily.

If the results are uploaded and your result has not been attached to your profile, there is an error in the information provided in your result. This has resulted in a new profile being created or the result being allocated to another runner. Possible reasons include an error in the spelling of your name / date of birth / nationality. If this is the case, please contact us by email at info@utmb.world, providing as much information as possible to help us resolve the issue.
