After the Olympic Games in Grenoble, Enderlein took first place in three out of five runs at the GDR Championships in Friedrichroda on 24 and 25 February 1968, ahead of Angela Knösel and Anna-Maria Müller. She was again awarded the Silver Patriotic Order of Merit in August 1968 for her athletic achievements and her "special merits for the increase of the international reputation of the GDR". Enderlein's performance suffered because of a shoulder injury. She finished sixth at the FIL World Luge Championships 1969 at Königssee, although she won the last heat, Petra Tierlich was first. A week before, Enderlein had won the 1969 Luge Alpine Cup in Imst, ahead of Lechner and Knösel. At the 1969 GDR Championships in Friedrichsroda, she finished outside the top three and fully retired from luge. Enderlein was named a "Verdienter Meister des Sports" (Deserved Master of Sport) and was awarded the Artur Becker Medal.
