Curious as to their training to become so dominant in XC and mountain running.
For world mountain championships. Men winning the individual title in 2009, 2013, 2014, 2015, 2017, and 2018. And winning the team title in 2013, 2014 2017 and 2018. They went from never even getting a bronze before 2009 to winning the individual title in 2009 and the team title in 2013.

And for World XC, though limited due to them changing it to every other year, but they crushed it in the last world championships on a actual xc course, not some flat fast golf course.
