 Riders race through the city streets tackling the steps and alleys, finding their own way through the ramps and jumps down to the "plan" (Valparaíso's "lowlands").The Valparaíso Downhill has been described by Chop MTB as "the craziest urban downhill race of all".Since 2005, a series of running events has taken place in the city with 5 km, 10 km, 21 km and marathon distances.
