Bull racing or "Karapan Sapi" is Madura’s traditional event. Races are held at weekends from August to September. The final will be held on September or October. These races date back to the 15th century. The bulls race in pairs. There is a wooden cart at the bull’s back, for the jockeys (7-9 years old boys) to ride the bull. The race tracks are typically about 100 meters long.
