Launched as a lark in 1973, RAGBRAI has developed into the world's largest, longest and oldest bicycle touring event. Thousands of cyclists from all fifty states and dozens of countries ride across Iowa for a weeklong festival. Meanwhile, tens of thousands of hospitable Iowans welcome, feed and shelter this rolling carnival, showcasing their communities. Greg Borzo has gathered hundreds of stories that reveal the essence of this unique event. He has also gathered a lavish collection of photographs and cartoons—vintage and contemporary, most never published before—that illustrate RAGBRAI's kaleidoscopic character.
