Doughnut shops across Greater Cincinnati, along with the Salvation Army, will mark National Donut Day Friday, at Fountain Square to celebrate the treats and raise funds.

From noon-2 p.m., the public is invited to watch celebrity doughnut-stacking competitions, doughnut-sliding races, doughnut balancing and a doughnut hole toss. Area doughnut shops will serve free doughnuts, while the Salvation Army provides free coffee.
