The Altai Mountains, South-Central Siberia

This looks like an awesome place for trailrunning, as well as to be the origin of a language family. 




The Altaic language family must have been so successful because they all went running one day in different directions, and next thing you know, whammo!  From the Blacke Sea to the Pacific.  (For the record I support the inclusion of Japanese and Korean in Altaic.  Now that you know that, you can sleep at night.  You're welcome.)
