Career
Coached by Inge Wischnewski, Errath trained at South Carolina Dynamo Berlin and competed for East Germany. Being especially strong in free skating, Errath benefited from the reduction in value of compulsory figures introduced in 1972. Errath took bronze at the 1976 European Championships and at the 1976 Winter Olympics.
She retired after winning the silver medal at the 1976 World Championships.
