The villagers of Kalliopi every year on 23th of April in the feast of Agios Georgios, they celebrate with horse races equal in spectacle and action to those of Siena.The ancient event, one of the most spectacular customs on the island, has its roots in the years of Ottoman rule.According to tradition, while the Turks were celebrating their Ramadan and were gathered in the mosque in Agios Ypatios, residents of Kalliopi went and stole their horses. Because they had nowhere to hide, they were prevented from running in groups to the nearby beach of Keros.Thus, horse racing was established around 1860.However, because the Turks did not like the equestrian competitions 
at first, as they say, Ai-Giorgis would come in their dreams when they fall asleep and beat them, as a result of which they would respect the custom of the Christians and also take part in the competiotions in honor of Ai-Giorgis.( Agios Georgios).Greek and Turkish riders descended in the races of April 23, on the day of the Saint’s grace, in different groups.The equestrian competitions of Kalliopi continue uninterruptedly from the middle of the 19th until today, with a short break of only two years in the war of the 1940s, because there were no young people in the village to fight. Nowadays, the inhabitants of Kalliopi and other neighboring villages, breed and train horses exclusively to take part in horse racing.The riders rise on horses without saddles, covering the distance of three kilometers from Agriones to the central square of the village.The first three winers riding on their horses, climb the stone carved entrance of the church of Agios Georgios of the 19th century, trophy bearers with a red handkerchief around their necks and are awardd by the priest to the applause and cheers of the pilgrims. The priest of Agios Georgios will cross the horse and give the rider as a prize a medal with a red ribbon while in the past a lamb with a red handkerchief tied around its neck.After the award in the courtyard of the church begins the feast with traditional spaces, food and wine organized by the Cultural Association ”Agios Georgios” Keros.
