In the Tour de France York was racing well even before the race reached the mountains with a third in the team time trial and ninth in the individual time trial on stage nine. York was placed tenth at this point. This improved further in the Pyrenees on stage thirteen from Pau crossing the Tourmalet, the Aspin, the Peyresourde and finishing at Superbagneres. York finished second on the day to eventual winner of the race, Greg Lemond. This placed York in fourth overall at this point and in the lead in the mountains competition. She retained this to the end of stage seventeen between Gap and Serre Chevalier. However York was battling illness and began to spiral down the placings in a struggle just to stay in the race. In the stage twenty time trial, in contrast to the ninth place in the earlier time trial, York placed 112th over ten minutes behind the stage winner (Hinault). York started stage twenty-one in fifteenth overall but climbed off her bike to abandon the race before the conical final climb of the day up the Puy de Dôme.
