Assessing the performance level of each trail runner, the UTMB Index is calculated for each of the 4 UTMB World Series race categories: 20K,50K,100k and 100M. Trail runners are also given a General UTMB Index calculated by combining results from all race categories.
Mandatory to enter the UTMB Mont-Blanc lottery, a valid UTMB Index is achieved by completing at least one race of the UTMB World Series or a UTMB Index race in the relevant category within the previous 24 months.
Finishing a UTMB Index race will contribute towards your UTMB Index. However, it will not provide Running Stones which are mandatory to enter the UTMB Mont-Blanc lottery for the World Series Finals. UTMB Index Races
UTMB INDEX PRIORITY REGISTRATION FAQS
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.
