GRAETTINGER, Iowa — A participant in an annual bicycle ride across Iowa has died due to a medical condition.

Officials with the Register’s Annual Great Bicycle Ride Across Iowa say 63-year-old Tom Teesdale, of West Branch, Iowa, died Monday.

RAGBRAI officials say Teesdale was treated on the route between Terril and Graettinger for a medical condition. He was then taken to Palo Alto County Hospital in Emmetsburg, where he died.

Teesdale owned and operated a business where he sold custom bicycles.

It’s the first time a RAGBRAI rider has died since 2010.

About 8,500 riders make the weeklong trip across Iowa, plus others who ride on single days.
