Basic explanation of the UTMB Index, UTMB Index Score and its categories.
What is the UTMB Index and UTMB index Score?
UTMB Index : Represents the overall performance level of a runner, it is calculated based on their best current scores.
UTMB index Score : A score given to each runner for each race they complete, evaluating their performance in that specific race.
The UTMB score is the number awarded to each finisher of a UTMB World Series Final, Major, Event race or UTMB Index race in the 20K, 50K, 100K and 100M categories depending on performance (boxed in blue in the image on the right). The UTMB Index is established by taking into account the 5 best scores (boxed in red in the image on the right).
What is a valid UTMB Index?
If a runner has completed at least one race in the past 24 months, then they will have a valid UTMB Index. If a runner has never completed a race or their last race is outside this time period, then they will not have a valid UTMB Index. The same rule applies to a UTMB Index by race category. See the full list of benefits for runners with a valid UTMB Index.
What is the difference between the General UTMB Index and the Category UTMB Index?
The General UTMB index uses the best results across all races greater than 20K.
The Category UTMB index uses the best results only in that specific category.
For a versatile runner, often their best 5 races will be spread across several different categories, which gives them a better result in the general index than they would have for each individual category.
