Daegu: Usain Bolt makes his season debut in the 100 meters on Wednesday at the venue that will host next year`s World Championships.
The Jamaican sprinter, the Olympic gold medalist and world-record holder in the 100 and 200, says he expects to run a "very fast time" at the Daegu meet.
It will be Bolt`s first 100 of the year after he skipped the opening Diamond League meet in Doha, Qatar, last week. He is due to run in Sunday`s Diamond League meet in Shanghai.
Veronica Campbell Brown, Carmelita Jeter, Lolo Jones and Dayron Robles are among other athletes who will test the conditions of the Daegu track ahead of next year`s worlds.
