In the ongoing World Athletics Championships at Beijing, two Indian athletes will be seen in action today. In the women's 800 metres event, national record holder Tintu Luka will be competing in the heats, whereas, the women's 3000 metres steeplechase finals will feature Shivaji Lalita Babar. Lalita Babar had earlier set a new national record while running in the heats.Meanwhile, Jamaican sprinstar Usain Bolt and his fierce rival Justin Gatlin of USA will be seen in the semi finals of the 200 metres event today. Last evening, Gatlin entered the semis with a far better timing than Bolt, a feat that he achieved in the 100 metres as well but only to lose in the finals.
