With silver in London, Rigoberto Uran is hoping to go one medal better in Rio on a course that suits him even better than the one four years ago.

The Colombian is a pure climber, but he is faster than most GC riders with the exception of Spanish duo Valverde and Rodriguez, and perhaps Dutchman Wout Poels and Irishman Dan Martin, so a sprint could se him medal.

"I like to course, it's very nice, so we'll see what happens," Uran said. "One day racing is very special, anything can happen and it is very difficult to control. The most important thing is that we have a good team and that I am healthy, and motivated and eager to do well. We have a good team of Colombians for this Olympiad and riders that can do very well."

Uran is joned by one of the strongest teams, aided by Esteban Chaves, Jarlinson Pantano, Sergio Henao and Miguel Angel Lopez.
