At the 1968 Winter Olympics in Grenoble , she initially finished fourth after the competition was halted to three runs due to bad weather , but was disqualified with her East German teammates Ortrun Enderlein and Anna-Maria Müller when it was discovered that they had illegally heated their runners ( which are used to guide the luge on the ice as it maneuvers down the track ) .
