Youngster running towards Olympic dream

The neighborhood boys shout at Mehboba Ahdyar when she leaves home. "Hero, hero! Look at the hero of our country," they yell at Ahdyar, one of Afghanistan's fastest female runners.

But the boys are not saluting a top athlete. Their sarcastic jabs are meant to poke fun at a teenage girl trying to realize Olympic-sized dreams.

Ahdyar, a 19-year-old middle-distance runner, is the only female on Afghanistan's four-member Olympic team.
