Washington, Aug 27 : Madonna has denied reports that claim the pop diva will run in Marathon des Sables next year.

Tabloid reports had earlier suggested that the 51-year-old hitmaker was under a strict training schedule for the six-day rigorous run across the Sahara Desert.

However, Madonna’s aide Liz Rosenberg has rubbished the rumours.

Contactmusic music quoted her saying: "It''s not true."

Dubbed as the toughest race on the planet, the 156 miles long trek is organized every spring and is the equivalent of six marathons. (ANI)
