What is the relationship between UTMB® Group and the Ultra-Trail® World Tour? What consequences does this new international circuit UTMB® World Series have on UTWT? 

The historical link between the UTWT and the UTMB® is first and foremost a sporting one. The main races of the UTMB® Mont-Blanc have been part of the UTWT since the creation of the circuit in 2014. Infact, UTMB® was one of the founding members of the Ultra-Trail® World Tour, along with the Western States Endurance Run, the Mount Fuji Ultra-Trail and the Ultra-Trail Australia. From a business perspective, UTMB Group bought the rights to the UTWT two years ago. We have therefore worked closely with the UTMB Group team, using our experience acquired during the last 7 years, to build this new UTMB® World Series together. It is not a circuit that will compete with the UTWT but rather a way to help the sport evolve. As a result, the UTMB® World Series marks the end of the UTWT in 2022.
