The Hardest Sport Climb In America: Seb Bouin Climbs Suprême Jumbo Love

In the fall of 2022, Seb Bouin makes a long-dreamed pilgrimage to Clark Mountain to try Jumbo Love—Chris Sharma’s iconic testpiece and the first route ever graded 5.15b. What starts as a single send attempt becomes a deeper journey into the history, mystique, and pressure that surround America’s hardest climbing. This is pure, high-stakes sport climbing: real effort on an uncompromising line, the tactics it takes to unlock a mega-route, and the emotional swings that come with chasing something legendary. If you want to feel what “hard” really means—where every move matters and commitment is everything—this film delivers.
