Washington's mayor, Adrian M Fenty, met with Giro officials last week, including during a lunchtime bicycle ride on Thursday.
The Giro's race director Angelo Zomegnan said: “We can’t say it will 100 percent start here, but we think that it is very, very possible and we’re moving forward to work together.
“There are a lot of things that must happen in the next few weeks before we can say it’s 100 percent. But I think it looks good.”
Fenty said: “I believe it would be one of the most fabulous events ever to happen in Washington, D.C., from an athletic discipline standpoint.
"This city is a world-class city, so we would be welcoming a world-class race inside of our borders.”
