More than 30,000 people participated Sunday in 21st Annual Susan G. Komen Race for the Cure at the Mall of America in Bloomington. Their entry fees will be used to seek a cure for breast cancer.

Coming so soon after the Boston Marathon bombings, the event had heightened security with a visible police presence and signs warning people not to leave bags and backpacks unattended.

Vikings cheerleaders were on hand and posed for photos with some participants.

Among those enjoying live music at the race was Lisa Kiffin, a 15-year survivor from Hibbing.

“It brings tears to your eyes when you see the sea of people,” said Kiffin.

The traditional Mother’s Day event included a 5k walk and activities in the Mall of America rotunda.
