RAGBRAI, The Register’s Annual Great Bicycle Ride Across Iowa, is an annual seven-day bicycle ride across the state. Heading into its 44rd year, RAGBRAI is the oldest, largest and longest bicycle touring event in the world.
For those of you who have never ridden, this rolling celebration of Iowa attracts participants from all 50 states and many foreign countries. It has covered thousands of miles through the years, and hundreds of thousands of riders have hopped in the saddle to pedal part of those miles.
RAGBRAI is a bicycle ride, not a race. It started in 1973 as a six-day ride across the state of Iowa by two Des Moines Register columnists who invited a few friends along. It is held the last full week in July. RAGBRAI is planned and coordinated by The Des Moines Register, and riders who participate in RAGBRAI understand that they do so at their own risk.
