Bolt looking to hone 200m technique in Paris

Olympic and world sprint champion Usain Bolt says he is hoping to demonstrate improved technique when he takes part in the 200m at the Diamond League event in Paris on Friday, taking on home favourite Christophe Lemaitre.

The 24-year-old, who defends his World Championship titles in South Korea this month, says "I'm just working on technique. It's all about execution."
