IOWA CITY, Iowa (AP) – Marathon dancers have raised nearly $2.6 million for the University of Iowa Children’s Hospital.

More than 2,300 dancers packed into the main lobby of the Iowa Memorial Union at the university campus in Iowa City. From 7 p.m. Friday until 7 p.m. Saturday, they gave up sleep, caffeine and the luxury of sitting down for 24 hours straight.

A Dance Marathon news release says each dancer raised at least $500 to participate. The money supports pediatric cancer patients at the hospital.
