Fundraising Incentives

The Children’s Tumor Foundation appreciates the time and energy our participants put into fundraising to help us end NF. We recognize their efforts through our NF Endurance Fundraising Club Program.

Once you reach your fundraising minimum for your event, you are eligible to earn a variety of great prizes!

Adopt-a-Hero Program

Through our Adopt-a-Hero Program, we partner NF Heroes (individuals living with NF) with our NF Endurance athletes to make your CTF experience more meaningful.

Our NF Heroes will motivate you throughout your training with emails, letters, photos and videos. They’ll share their story of what it’s like to live with neurofibromatosis.

Do you know an NF Hero? They can join our Adopt-a-Hero program and help inspire our athletes! Email us at nfendurance@ctf.org to learn more or sign up.
