The new iPhone app called "Zombies, RUN!" is not your standard running game.
It's designed to encourage folks, such as say, video gamers, who aren't usually associated with exercise to take up running.
British writer Naomi Alderman, who is a gamer herself as well as an Orange-award winning novelist, came up with the idea for "Zombies, RUN!" while in a class for amateur runners she tells weekends on All Things Considered guest host Mary-Louise Kelly.
"The start of the course they said to us, "Why do you want to learn how to run?" and one woman said, "I want to be able to out run the zombie hoarde," Alderman explains. "Then I thought, 'Ahh, this would be a good idea for a game.'"
