(CNN) -

Ahead of Wednesday's debate between President Barack Obama and Republican challenger Mitt Romney, GOP vice presidential candidate Paul Ryan will roll through the battleground state of Iowa on a two-day bus tour.

Billed by the Romney-Ryan campaign as the Real Recovery Bus Tour, Ryan will make stops on Monday and Tuesday in Dubuque and Clinton along the state's eastern border.

The Romney campaign said in its announcement Saturday that additional events in eastern Iowa would be announced.

The two GOP candidates set out on a three-day bus tour of Ohio last week. Democrats responded with a tour of their own along the Romney-Ryan route.

Ryan made stops in New Hampshire and Ohio on Saturday, including two rallies. He also took in the football game between Ohio State and Michigan State at a sports bar in Columbus.

Recent polls in Iowa showed either Obama as slightly ahead of Romney or that the two were engaged in a close race within the sampling error.

Early voting in Iowa began last Thursday.

Romney and Obama debate Wednesday evening in Denver, Colorado.
