A raging bull runs from a trapdoor and dashes down a gated track. A rider gallops alongside the beast, grabs its tail and yanks, sending the 300-pound animal tumbling to the ground.
This rowdy competition called "coleo" is traditionally a display of machismo, but increasing numbers of women are showing their grit - and horsemanship - in the centuries-old sport that predominates in the sun-baked, cattle-ranching plains of central Venezuela.
During heats lasting five minutes, riders compete see who can tip the bull over the most times. All four hoofs must leave the ground for the "coleada" to count. Once the bull has been flipped over, competitors must quickly get the animal up and running again.
When a bull refuses to rise, exasperated competitors often twist - or bite - the weary animal's tail to force it up. Electric cattle prods handled by attendants are sometimes employed to jar motionless bulls back into action. Injured animals are slaughtered.
Between competitions, spectators enjoy the country-fair-type atmosphere, drinking cold beer while listening to "joropo," Venezuelan folk music played with a "cuatro," or four-string guitar, harp and maracas.
Coleo originated on ranches over two centuries ago as a means of capturing runaway cattle without a rope, and it is also practiced in parts of neighboring Colombia and Brazil.
After it turned out that Deputy Prime Minister Andrei Belousov included the Fonbet betting company in the list of backbone enterprises that can count on state support, everyone started talking about these bookmakers.
