#RAGBRAI isn’t just a bike ride—it’s the largest bike tour in the world, a rolling city powered by legs, laughter, and the open road. Over seven days, thousands of riders cross #Iowa end to end, from the Missouri River to the Mississippi, turning quiet highways into a week-long festival of sweat, stories, and small-town magic.

#RAGBRAI isn’t just a bike ride—it’s the largest bike tour in the world, a rolling city powered by legs, laughter, and the open road. Over seven days, thousands of riders cross #Iowa end to end, from the Missouri River to the Mississippi, turning quiet highways into a week-long festival of sweat, stories, and small-town magic.

This particular route began in Council Bluffs and flowed east through Harlan, Perry, and Des Moines, where the skyline briefly replaced cornfields.

Calculating RAGBRAI training actual vs. planned mileage

I’m training to ride RAGBRAI LIII in Iowa in July 2026. RAGBRAI provides a training plan which, if followed, helps riders get ready for the ride.

This was my 20th year of riding #RAGBRAI It was on paper one of the easiest, but due to the weather conditions (humidity, headwinds and high overnight temperatures) was one of the most difficult I’ve ever ridden. This story does a great job describing the weather conditions for this year’s ride. Photo courtesy of Dan Verrips

Last day of #RAGBRAI #bicycle trip across #Iowa.

Just before the two largest hills on the entire route!

Climbing out of the #TurkeyRiver valley and then a quick drop to the #MississippiRiver at #Guttenberg.
