Strap in as Czech rider Tomas Slavik marks the 15th anniversary of the Red Bull Valparaíso Cerro Abajo #mountainbike ride.
With Bernardo Cruz riding in front of him, he tackles what he calls "one of the hardest urban races in the world" with a #gopro attached to his helmet.
They hurl themselves down steps, tackle jumps and fly past gated properties on streets lined with spectators.
The perils of such an undertaking are all to see as Cruz briefly comes a cropper, falling to the ground, with Slavik also at one point joking "we made it, still alive".
