(Radio Iowa) – The Register’s Annual Great Bike Ride Across Iowa is still over a month away, but a group of riders will make an early trek along the entire route beginning this weekend in Sioux City, the starting point for this year’s event. Sergeant Mark Huberty, of the Sioux City Police Department, says a group of riders will begin a preview ride of the RAGBRAI route on Sunday morning that will be used by thousands of riders in July.

Those riders will pedal the entire RAGBRAI route in the upcoming week, checking it out ahead of the annual bike ride across Iowa.

RAGBRAI begins its 50th anniversary in Sioux City on July 23rd and ends the following Saturday in Davenport.
