Veteran French female cyclist Jeannie Longo is back in the crosshairs of national anti-doping authorities for failing to comply with procedures aimed at catching drug cheats.
The head of the French anti-doping agency, the ALFD, said Longo was again "obliged to provide details of her whereabouts" so that she could be subjected to surprise tests.
ALFD president Bruno Genevois told AFP the measure was ordered "in the light of previous failings" by the cyclist.
Longo, aged 54 and still racing, had received three warnings from the French Anti-Doping Agency for breaking the whereabouts rule.
Longo is a sporting icon in France, having won 59 national titles, 13 world titles and four Olympic medals including a gold in road racing in 1996.
She has however seen her reputation tainted by a string of doping allegations.
Her husband and coach, Patrice Ciprelli, admitted last year that he had been buying the banned blood booster EPO since 2007, but insisted it was for his own, personal use.
