The rain held off Saturday morning making for perfect conditions to walk for a great cause.
The JDRF One Walk was held at the Iowa State Fairgrounds.
It's one of about 200 races to find a cure for Type 1 diabetes held around the country.
6,000 people participated in the three mile walk.
Before a single step was taken, groups collected donations.
Families affected by the disease hope events like this help researchers get one step closer to putting an end to this disease.
"My daughter was diagnosed in October and it’s our goal to turn type one into type none so one day, she can be insulin independent and all of those are people here today can too,” said Steve Mauro, a parent.
The fundraising goal for Saturday's walk was $1 million.
