SHEFFIELD, England — American sprinter Tyson Gay would rather break the 100-meter world record in Britain than on his home soil.
Gay, the world's fastest man this season, said interest in the United States is minimal and he's fed up with questions about doping.
The Grand Prix meet Sunday would be a perfect venue for Gay to better Asafa Powells world mark of 9.77 seconds. In February, Gay ran 9.76 in New York, but the wind was measured at 2.2 mph slightly above the allowable margin of 2.0.
"I would love to break the record over here," Gay said Friday. "I think it was a good thing I didn't break the record in the United Sates considering the wind conditions. It was a small meet in New York. There weren't a lot of people there. So I would like to do it around a lot of appreciative track fans."

Powell equaled his own mark at Sheffield's Don Valley Stadium last year. The Jamaican is not running here this year, and its unlikely Powell and Gay will race against each other until next month's World Championships in Osaka, Japan.
Gay was undeterred Friday by the downpour in Sheffield and a slightly swollen knee. He believes adrenaline will help against a field that includes fellow Americans Leonard Scott and Shawn Crawford.
"I really believe if I get the right conditions it can happen," Gay said. "Rain doesn't necessarily mean you are going to run slow. In Lausanne, I ran pretty fast (to win the 200 on Tuesday) and it was cold. Sometimes conditions also can mean just the crowd, just excitement."
Gay ran 9.84 into a strong headwind at the U.S. championships last month, then won the 200 two days later in 19.62, the second-fastest time in history.
He is angry that the sports reputation has been damaged by repeated doping scandals.
"I want to run faster than the guys who were running when they were using performance enhancing drugs and that will change their minds," he said.
"When I started running good at the beginning of the year in the U.S., I was getting a lot of drugs questions," Gay said. "Over here I'm not getting too many and I really appreciate that. You can really come out and have fun and not worry about if I run fast someone will put something in the newspaper about me. That's what I have to worry about in the United States."
