It's a special breed of racer who squeezes around the corners of South American cities, shoots down the narrowest stairs and tests the limits of grip on asphalt. Riders like Tomáš Slavík are more likely to be seen at fourcross races, where they still exist. In addition, there is an armada of riders from Chile, Brazil and Argentina who feel at home in the steep lanes. 

For the 21st edition, the organizers of the race in Valparaíso have given it a new first half. As soon as they start, the riders squeeze through a narrow door, pushing hard in a family's living room to make it from their balcony to the landing ramp. 

The key passage is a seemingly endless staircase, a wall on one side, a railing on the other and both so close together that most riders mount handlebars as narrow as you've seen at downhill races since the nineties.

The race is also decided on the "Moto GP" section, a series of bends on an asphalt road that is the undoing of several riders, because at some point you just can't put the bike even flatter into the bend without lying down completely. 

Tomáš Slavík won the race in the Chilean coastal town for the first time in 2015. In 2025, at the age of 37, he takes victory number four. With a winning time of well over two minutes, he beat local Felip Agurto by just 21 hundredths of a second.
