Bolt wants roof over his head for Polish race

Six-time Olympic champion Usain Bolt is hoping the roof will be closed when he runs his first race in Poland at the Kamila Skolimowska Memorial in Warsaw on Saturday.

The Jamaican world record holder will have his eyes on a special mark when he competes over 100 meters on a newly laid track at Warsaw's National Stadium, which has a retractable roof.

"I've never run indoors, I was always too tall," Bolt joked at a news conference on Wednesday. "When I heard there was going to be a roof, I was looking forward to that."
