RAGBRAI is an acronym. It stands for Register’s Annual Great Bicycle Ride Across Iowa. The Des Moines Register is a newspaper that claims to be the number one source for news and information in Des Moines and across Iowa.
The history: “In the beginning, when a few friends got together for a casual bike ride across Iowa in 1973, no one imagined that a tradition would be born, let alone that it would become the longest, largest and oldest recreational bicycle touring event in the world.”
