MASON CITY, Iowa (AP) – Two eastern Iowa men are attempting to run marathons in each of the state’s 99 counties. The Mason City Globe Gazette reports that 44-year-old Dennis Lee of Walford and 30-year-old Daren Schumaker of Cedar Rapids plan to run in their 86th county, Cerro Gordo, on Saturday.

The men say the idea was born because both of their lives have been altered by losing family members to heart disease and strokes. The runs are intended to raise awareness and research funding for the American Heart Association. Lee and Schumaker will run a 100th marathon after running all of the counties. The final run will take place in the county that donates the most to the American Heart Association.
