- Contador is one of the most decorated cyclists of all-time with seven Grand Tour victories in total to his name and is one of only six riders to win all three of the Tour de France, Giro d'Italia and Vuelta a Espana.
- Froome will also be the man to beat in the Vuelta if Contador is to have a glorious goodbye from the sport as the Briton headlines a strong field also featuring Fabio Aru, Vincenzo Nibali and Romain Bardet.
- The race starts in Nimes, France before ending with a traditional ride around Contador's home city of Madrid on September 10.
Two-time Tour de France winner Alberto Contador announced on Monday that he will bring his illustrious career to an end next month after racing in the Vuelta a Espana on home soil.
"I would like to inform you about two things. One is that I will participate in the next Vuelta a Espana from August 19 and the second is that it will be my last race as a professional cyclist," Contador, 34, said in a video posted on his Instagram account.
Contador is one of the most decorated cyclists of all-time with seven Grand Tour victories in total to his name and is one of only six riders to win all three of the Tour de France, Giro d'Italia and Vuelta a Espana.
"It's a decision that I have thought through and I don't think there is a better farewell than in the home race and in my country," Contador added.
"I'm sure they will be three wonderful weeks, enjoying all your affection, and I can't wait to get started."
Contador shot to fame with victory in the 2007 Tour de France with the Discovery Channel team before joining Astana in 2008.
He was unable to defend his yellow jersey at the Tour as the Kazakh team were banned from competing by organisers due to previous doping offences, but Contador made the most of his exclusion by winning both the Giro and the Vuelta in 2008 before landing a second Tour de France in 2009.
However, Contador's career was also overshadowed by a positive test for the banned substance Clenbuterol during the 2010 Tour.
