Bolt back to basics in preparing for Beijing

Reigning world and Olympic sprint champion Usain Bolt will return to basics when he runs the 100 meters on Thursday at the Jamaica Athletics Championships to prepare for the August World Championships in Beijing.

Bolt had not originally planned to run at the national trials for the Jamaican squad that will compete at the worlds, having already assured himself of a spot in the field.

But his failure to run under 10 seconds in the 100 or under 20 seconds in the 200 so far this season has bewildered the global sprint star and forced coach Glen Mills to change plans and enter him in the Jamaican trials that selects athletes for the worlds and next month's Pan American Games in Toronto.
