A look at a few of the major accomplishments over the past quarter-century by athletes who were past the age of 40:

_Dara Torres: At age 41, the swimmer wins two events at the 2008 U.S. Olympic Trials, the 50- and 100-meter freestyles, setting an American record in the 50 free. She has opted not to compete in the 100 free at the Beijing Games.

_Eamonn Coghlan: In 1994, the 41-year-old Irish miler and former world champion at 5,000 meters becomes the first person over 40 to run a sub-4 minute mile. Coghlan clocks a 3:58.15 at a race in Cambridge, Mass.

_George Foreman: In 1994, at age 45, the boxer regains part of the heavyweight title he lost to Muhammad Ali 20 years earlier, stopping Michael Moorer with a two-punch combination in the 10th round. Foreman captures the IBF and WBA championships to become the oldest champion in any weight class.

_Jack Nicklaus: In 1986, the golfing great wins his last major championship, the Masters, at age 46.

_Nolan Ryan: In 1990, at age 43, threw the sixth no-hitter of his career, blanking Oakland 5-0 while pitching for the Texas Rangers. The next season, at age 44, Ryan tossed his seventh no-hitter against the Toronto Blue Jays.

_Darrell Green: Elected to the Pro Football Hall of Fame in February in his first year of eligibility, the Washington Redskins cornerback was 42 when he retired after the 2002 season. He had at least one interception in 19 consecutive seasons.

_Martina Navratilova: A month before her 50th birthday, in 2006, the tennis champion finished her career by winning her 59th Grand Slam title, teaming with Bob Bryan to take the mixed doubles championship at the U.S. Open.
