Alberto Contador is looking forward to a long retirement after taking part in the Shanghai Criterium on Sunday.
The Trek-Segafredo rider bade his farewells at the end of the Vuelta a Espana in September but was involved in the Japan Cup Criterium a fortnight ago before taking part in Shanghai this weekend.
"For me it's a special day. I consider it as something symbolic. My last day with a professional licence," Contador said.
"I have to say that the Vuelta was my final bow, but it's true that it's nice to have the chance to say goodbye here, alongside some of the biggest names in the peloton, and in a different cultural environment."
Contador finished ninth at the Tour de France in July, but insists he will not miss cycling on a professional basis, adding: "I no longer have to go out on the bike every day but you can put that energy into other things. I have lots of great opportunities for the coming years.
"You have to have something to motivate you when you get out of the bed in the morning, and I have many."
The Spaniard turned professional with the Once-Eroski team in 2003 before moving to the Discovery Channel squad four years later. He won the 2007 Tour de France before heading to Astana the following year.
He won the Giro d'Italia and Vuelta a Espana in 2008 before claiming his second Tour de France victory in 2009.
After moving to Saxo Bank-SunGard in 2011 Contador won the Vuelta a Espana in 2012 and 2014 before clinching the 2015 Giro d'Italia.
Chris Froome is 100/1 to win the 2018 Tour de France while Nairo Quintana can be backed at 4500/1.
