Tyson Gay focusing on 100m in Olympic season

US sprinter Tyson Gay, hoping to put seasons hampered by injury behind him, says he's focusing his 2012 Olympic season efforts on the 100 metres. On a day when Gay held an open workout attended by several media outlets, he told ESPN.com that he doesn't think his post-injury training allows him to attempt a sprint double. "I've had some minor setbacks with nagging injuries," Gay told ESPN.com. "I've been taking it slower, and I don't have the same quality I wanted to do the double." Gay's 2011 season ended in July when he had arthroscopic surgery to repair a torn labrum muscle in his hip. He says the injury is healed but adductor muscle strains and inflammation around his pubic bone have cost him training time since November. He has been training on grass rather than on the track in an effort to putt less wear on his body, and doesn't even know when or if he'll race before the US Olympic trials at Eugene, Oregon, in June. "Maybe I want to pick a race before trials, or maybe just run at trials and see how it goes," Gay said. "I'm just not going to have the opportunity to have a lot of races like I normally do." Gay has endured a frustrating few years, including a hamstring injury in a 200m heat at the 2008 Olympic trials. In 2009 he had a groin injury, followed by last year's hip injury. However, he'll give it all he's got to defend his 100m title at the US trials -- a cut-throat competition that for many US athletes is more stressful than the Games themselves. "The trials are tough," Gay said. "I know all these guys are going to be gunning for me, gunning for that spot, gunning for glory. I want to defend my championship and get to London." There he would like to take on the world's best -- expected to be led by Jamaican Usain Bolt -- and fill a gap in his resume with an Olympic medal, preferably gold. "I put some pressure on myself because I want to get it accomplished," said the 29-year-old, who won the 100m and 200m at the 2007 world championships. "That's my goal. I want an Olympic medal -- to come home with it. "I'm never going to be satisfied, but I would be satisfied in that area with a medal."
