Dear runner,

Is an historic day for the UTMB® community, as we unite around our shared values of daring, the spirit of amazement and preservation of our mountain playgrounds, to announce the creation of the UTMB® World Series, and a new partnership between UTMB Group and The IRONMAN Group.

Since the creation of the UTMB® Mont-Blanc 18 years ago, UTMB Group have always been passionate about creating strong links with the entire trail running community. Driven by that same passion, we are thrilled to be able to reveal a new, inclusive World Series that will bring the UTMB® experience closer to all runners around the globe, and to invite you to be part of it.

New exclusive services and simplified access to the UTMB® Mont-Blanc
