Khalifa International Tennis and Squash Complex in Doha hosted the WTA Tour Championships in women's tennis between 2008 and 2010. Doha holds the WTA Premier tournament Qatar Ladies Open annually. Since 2002, Qatar has hosted the annual Tour of Qatar, a cycling race in six stages. Every February, riders are racing on the roads across Qatar's flat land for six days. Each stage covers a distance of more than 100 km, though the time trial usually is a shorter distance. Tour of Qatar is organised by the Qatar Cycling Federation for professional riders in the category of Elite Men.
