Karapan sapi is a traditional bull racing festival on the Indonesian island of Madura.[1] Every year from about July through October, local bulls are yoked to wooden skids and raced for 130 meters, similar to a chariot race.[2] There are several of these races throughout the season, and there is a final trophy race held in Pamekasan. The bulls participating in the event are adorned with gold and other decorations,[3] and the event may be accompanied by Gamelan music, food, and wagers on the outcome of the race. A depiction of the festival was featured on the reverse of the 100 rupiah coin for Indonesia from 1991 to 1998.[4] Indonesian stamp in 2009 also depicted the race along with Surabaya–Madura Bridge.
