Walkers is too fast an adjective, Limpers would be a better term
I can walk faster than these things easy.
Alone, walkers a more vulnerable, but in groups and herds, they are strong. Look at the scene when Rick was in Atlanta. That number of walkers would have easily killed him if he didn't find that tank.
And remember that they live in a world where the term zombie doesn't exist. They started seeing the people around them attacking other people. Like they gone mad.
It might be a good idea to watch the Webisodes. They give you background info about the start of the apocalypse.
so basically you're playing pacman...
