Subida Impossível (Impossible Climb) is a challenging motocross hill-climbing event in Portugal that more than lives up to its suggestive name.

Every year, dozens of experienced motocross bike riders gather in the Portuguese city of Silves for a chance to become legends among their peers. Subida Impossível is one of the toughest motocross challenges in the world, requiring perfect control of the bike in order to complete a 110-meter-long course up a rocky hill. 110 meters may not seem like much for professional riders, but keep in mind that in some places, the gradient is over 80%, not to mention the unpredictable terrain and a very narrow course. Let’s just say that it’s not called Impossible Climb for nothing and that there is a reason why only a handful of participants have completed the hill climb in over two decades.
