When Sheila Powers was 40 years old, she learned how suddenly and unexpectedly heart disease can strike.

The York Township resident experienced and survived a heart attack, and will serve as the 2012 York County Heart Walk Heart Hero on Sunday.

"Luckily, I am a nurse and knew the symptoms of a heart attack very well and had the support of my husband and two daughters to help me recover," Powers said.

Powers will participate in the York County Heart Walk, which begins at 1 p.m. at John Rudy County Park, 400 Mundis Race Road.

Registration begins at noon.

Walkers who raise a minimum of $100 will receive a Heart Walk T-shirt and the chance to win other prizes based on their fundraising levels.

The event is family- and pet-friendly and features a one mile and three mile walking route.

There will be blood pressure screenings, and face painting, education and activities for children all day.

Everything will be held rain or shine.

The Heart Walk is a great way for companies to not only support the American Heart Association but to get employees to be active in their own health and the community, said Katie Miles, Heart Walk chairwoman and vice president at the York County Economic Alliance.

More than $49,000 was raised at the Hanover Heart Walk held on Sept. 16. The combined fundraising goal for the two events is $110,000.

The Heart Walk raises funds for the American Heart Association to fight heart disease, the number one killer in the United States.
