As of Thursday, Iowa State’s Dance Marathon is just 99 days away. 

The 2016 Dance Marathon at Iowa State will begin Jan. 22, 2016, and continue for 24 hours.

The event raises money for the University of Iowa Children’s Hospital, which helps children with life-threatening illnesses. This will be the 18th Dance Marathon at Iowa State. Last year’s fundraisers brought in $444,000 for the organization.

When a fundraiser achieves more than $250 in donations, it is invited to the dance party. The fundraiser will then sign up for one of two 12-hour time slots, when they dance, play games and interact with the children they’re supporting. 

The first Dance Marathon raised $20,000, and the organization has now raised, in total, more than $2.7 million for the University of Iowa Children’s Hospital.
