My Xtreme Hike Story
Heidi Provencher
Fundraising for Yosemite Xtreme Hike 2026
Heidi Provencher
There is currently no cure for cystic fibrosis and too many people with CF die young. I’m hiking to help change that reality.
This year, my mom and I are doing the Extreme Hike in Yosemite, to cap off a year of outdoor activities including snowboarding and rock climbing, as well as to celebrate my 18th birthday. This hike has been a goal of mine for years, since when I was a young kid who would go to explore Yosemite with my grandma while my parents did it. I am excited to make this goal a reality, as well as to explore the incredible nature that Yosemite has to offer now that I am older.
Will you help us end cystic fibrosis?
By donating to my fundraising goal, you have the power to advance the research and science needed to drive our shared dream forward – a cure for everyone with CF.
