Hike to Cure Cystic Fibrosis

The Cystic Fibrosis Foundation’s Xtreme Hikes are an incredible way to raise awareness and funding for cystic fibrosis, while putting your personal endurance to the test. Cystic fibrosis is a progressive genetic disease that affects the lungs, pancreas, and other organs. While progress has been made, we still lose precious lives to CF every day.


When you participate in an Xtreme Hike, you join others who want to make an impact while experiencing the joy, challenges, and personal triumphs associated with hiking through some of our nation’s most scenic and rugged trails. 


An Xtreme Hike is more than just a hike; it's a remarkable adventure. According to many in our community, it’s an experience that stands out. This all-inclusive, weekend-long event pushes you to your limits, with hikes of up to 30 miles in some locations, all while making a difference in the lives of those with CF. 


Your participation is crucial in helping us achieve our shared dream of a CF cure. To achieve this goal, more research is essential, requiring a very substantial investment. Even after a cure is found, customized care will be needed for generations to treat long-lasting health problems, making continued donor support vital. Fundraising is critical to advance our mission, and now is the time to act. Help us find a cure for cystic fibrosis.

2025 National Ambassadors

Meet your 2025 National Ambassadors, Alexis Vargas and Caroline Lewis!

KENTUCKY-WEST VIRGINIA CHAPTER

Alexis Vargas

Alexis was not diagnosed with cystic fibrosis until she was 5 years old. Despite chronic lung infections and violent coughing episodes, the military hospital where she was born never tested her for CF. After receiving her diagnosis, the Vargas family walked in their first Great Strides. This is Alexis’ 14th year participating, and she now walks in the Lexington/Winchester walk.

NORTH CAROLINA CHAPTER

Caroline Lewis

Caroline was diagnosed with cystic fibrosis at 10 days old. She is a champion for the North Carolina Xtreme Hike community, and has participated in three Xtreme Hikes since she was able to start hiking at 14. When she was an infant in 2010, her dad participated in the inaugural North Carolina Xtreme Hike while she did nebulizers from the car.
