Collect Running Stones
The UTMB World Series Events and Majors allow you to collect Running Stones to enter the UTMB Mont-Blanc where the prestigious UTMB World Series Finals will be held each year.
From now on, you need to have at least 1 Running Stone acquired in the past two years to enter the UTMB Mont-Blanc lottery. You can only collect Running Stones by finishing a UTMB World Series Event or Major. Each Running Stone improves your odds in the lottery.
