France's Bryan Coquard took a lead in the Olympic omnium thanks to a commanding win in the elimination race. The omnium is a test of all-round skills over two days in six disciplines: a flying lap, 30-km points race (20 km for women), elimination race, 4-km individual pursuit (3km), 15-km scratch race (10km) and one-kilometre (500m) time trial. The last three events will be held on Sunday.
