Athletes should decide for themselves.  In sports it is crucial that the best person wins no matter of his or her sex. We should let the women decide if they are prepared enough to participate in men’s events, and not take that decision for them by forcing them into set leagues. American skier Lindsey Vonn has won the women's World Cup four times. In November 2012, she asked to be allowed to compete in the men's event. The request was denied(1). If a female athlete can perform better than a male athlete in a certain discipline, she should be allowed to compete with, and beat, the male athlete. The examples of Danica Patrick, a “NASCAR driver who won the 2008 Indy Japan 300 and finished 3rd in the 2009 Indy 500” and Seena Hogan who holds multiple records in ultra cycling, which haven’t been beaten by any man or women to this day(2), show us how women can improve a competition in a significant way. At the end of the day, it doesn’t matter who wins, the very purpose of sports forces us to let them take the decision, as we cannot accurately suppose that women are worse than men at every single competition of every single sporting event as shown by the stated examples.
