UTMB INDEX RACES
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.
Your UTMB Index also allows you priority access for registration at UTMB World Series Majors and Events and is sometimes required as a security measure by Race Organizers, in order to ensure that you have the experience necessary to complete an ultra-distance.
