The American's Cancer Society's "Making Strides Against Breast Cancer" walk started at Howard Park this morning.
The 5k walk led participants through the downtown streets of South Bend.
The money raised from this event helps provide free resources and support to men and women newly diagnosed with breast cancer.
It also funds research and helps give access to mammograms to people who need them.
Last year, this walk had 2,000 participants and raised more than $200,000.
