Jamaica's Usain Bolt sprints past doping questions

The world's fastest man also boasts a neat sidestep.

Usain Bolt, the 28-year-old sprint great from Jamaica, artfully dodged questions about doping in track and field and his rivalry with twice-suspended US runner Justin Gatlin during a meeting with a select band of journalists in Beijing on Thursday.

Bolt dashed to worldwide fame at the 2008 Beijing Olympic Games by claiming the 100-, 200 - and 4x100-meter titles, a feat he repeated in London four years later. Toss in eight world championship golds and he is moving along quite nicely.
