Thousands of visitors head more than 1,100 feet underground each year to tour Ruby Falls, but this month they're also taking steps to raise awareness for heart health. Lots of steps.

Ruby Falls President Hugh Morrow is hoping they take 100 million steps collectively.

"This is our second year to do this, our 100 million step march which plays off the month of March, second year with the American Heart Association," Hugh Morrow, President of Ruby Falls, said.

Morrow said they partner with the American Heart Association for Go Red For Women, but they wanted to do more than just a one-day partnership.

"This way we can get all of our thousands of visitors involved and going heart healthy through the month of March as they tour our facility," Morrow explained.

Guests are also encouraged to sign a banner to say they've been exposed to heart-healthy initiatives and information.

Heart disease is the number one killer of both men and women. It is responsible for about one in every four female deaths, and almost two-thirds of women who die suddenly of coronary heart disease have no previous symptoms

Morrow said Ruby Falls provides the perfect place to not only visit but to raise awareness and be heart healthy.

"It's important, and it takes 2,700 steps to do a round trip out to the falls and back," Morrow said.

We caught up with some of the guests who like the idea that their tour was about much more than just fun.

"I think it is really important and my sorority back in Kansas does heart healthy as well so that's really cool that we came here and visited this place to," Lindsey Pitzer said.

Pitzer said she tries to stay active and eat right, so this fits right in with her healthy lifestyle.

"So it's great exercise, it's a great group outing and it's a great way to spend time with the ones you love," Morrow said.

Eleven-year-old Amanda Pitzer, who says she also likes to stay active and healthy, agrees.

Amanda Pitzer says "It's my first time here, and I think it's really cool."
