ANDORRA LA VELLA (Reuters) - Joaquim Rodriguez will end his professional career at the end of the year, the Spanish rider said on Monday.

"2016 will be my last season as a professional rider. I still enjoy this sport so much but I'm 37 years old," Rodriguez, who finished three times at the top of the world rankings, told a news conference on the first rest day of the Tour de France.

The Katusha rider also has five grand tour podium finishes to his name - three on the Vuelta, one of the Giro d'Italia and one on the Tour de France.

After a solid opening block of racing, Rodriguez, nicknamed "Purito", is fifth overall in the Tour de France.
