Attack While Running

Hello Unity3D.I have a question about doing animations while running.How can i make it that my character does a certain animation while running and only while running?For example.My characters do certain punches and kicks while standing still.But when i run i want them to do a special punch,such as a superman much or a special kick,such as a back kick.If anyone knows how i can do this.Can you please tell me how?(I can't find any scripts for this for some reason).
