Soloman Running's video series, Kilian's Quest, highlights Kilian Jornet, a Spanish long-distance runner, mountaineer and mountain biker. The latest episode finds Jornet running in the Tetons with our friend, Anton Kupricka, pictured above on the Flatirons in Boulder, CO. The video, titled "Coming Back," is really something special, and if you speak Spanish, you'll enjoy it even more. Watch it here.
