Cystic Fibrosis is a devastating genetic lung disease that routinely kills its victims before they get out of their teens.

But research and treatment have progressed and in the past year the average age for a patient passed 18-years-old.

Cystic Fibrosis patient, Allison Burke: "I'm 31. When I was born, the life expectancy was five. So being 31- and being here and being able to walk around and do things is incredible."

This year the Cystic Fibrosis foundation aimed to raise $41 million to develop new treatments and ultimately a cure for Cystic Fibrosis.

This year is the 30th anniversary of the "Great Strides" fundraiser.
