Masooma Alizada (L), and Zahra Alizada (R), member of Afghanistan's Women's National Cycling Team exercise on the outskirts of Kabul February 20, 2015. Afghanistan's Women's National Cycling Team has been breaking new ground for women's sports and pushing the boundaries of what is - and is not - acceptable for young women in the conservative Muslim country. Under the Taliban in the 1990s, women in Afghanistan were excluded from public life, banned from going to school or stepping outside their home without a male family member. Women's rights have made gains since the hardline Islamist group's ouster in 2001, but observers worry that progress is at risk as gender-based violence persists and women remain under-represented in politics.

Colombian disabled athlete Robinson Martinez (bottom) swims alongside an unidentified woman inside a sports center in Cali, in this photo taken May 21, 2004. Martinez, whose left leg was amputated at the age of five to save his life from a snake bite infection, is training to compete in the Athens 2004 Paralympic Games in three different cycling events. His love for bicycles started when he was small, soon after losing his leg. He recalls, "At the beginning it was difficult to dominate the bike, but one gains confidence and learns to balance better as time goes by." Martinez is cautiously confident about his chances in Athens. "I just pray to God that he give me the strength in my leg and the heart to be champion."
