GOLD COAST (AUS): Caster Semenya has said she has “mastered the art” of running the 1500m, informs the Independent Online. “It is a tougher race to run but – coming from the world championships we’ve learned from that race. I think we’ve mastered the art of running the 1500 and I don’t think it would be a problem. I’ve run a 4:10 and a 4:02 on my own, taking the lead from the start, which shows I have improved. All I need to do now is to go and execute and secure my gold,” she said. Semenya is targeting both the 800m and 1500m at the Commonwealth Games and will be looking to emulate Kenya’s Nancy Langat who claimed both titles in 2010.
