World Athletics 2011: Cram on Ohuruogu, Bolt and Farah
Steve Cram looks back on an eventful first day at the World Athletics Championships and forward to Sunday, when Usain Bolt and Mo Farah go for gold in South Korea.
Christine Ohuruogu was disqualified from the 400m for a false start, Bolt was the fastest qualifier in the 100m and Kenyans dominated the women's distance events on Saturday.
On Sunday there are the finals of the men's 100m and the men's 10,000m, where Britain's Farah is considered favourite.
