We can’t wait to bring the CF community together for Vail Xtreme Hike!

We are excited to return to Vail, Colorado for a full weekend event this September. All hikers will receive a two-night stay at the Vail Marriott Mountain Resort, from September 17th-19th, as well as all meals for the weekend. During your hike on Saturday, you will have the opportunity to do up to 20 miles on Vail Mountain, but your total distance is up to you. Volunteers will be available to help you choose your trail and support you.

Register. Register and participate in this year’s Xtreme Hike event and help us stay the course and advance our mission in an uncertain time.

Recruit. Recruit others to participate with you! Hike weekend will be more fun with friends, family, and co-workers.

Fundraise. Fundraise online by leveraging the tools in the Participant Center, the Fight CF mobile app, and Fundraise on Facebook to reach your goal. Create a passion fundraising event by developing a fundraising event through your favorite hobby, activity, or passion.

Train for your Journey. Wear an Xtreme Hike shirt, team shirt, or your Cystic Fibrosis Foundation branded apparel, while you hike on your own local trail or within your neighborhood!  Track your activity on the Fight CF mobile app so you can hike with others participating in the event and across the country. Share your training this year by sharing your story and posting a selfie on Facebook, Twitter, and Instagram.  Make sure to tag the CFF Rocky Mountain Chapter and use the hashtag #XtremeHike to keep the energy and momentum going strong!
