We put the thrill in “thrill-anthropy” and want you to join our amazing community of do-gooders who are helping to fund life-saving research for people with neurofibromatosis (NF). Whether you’re dropping your pants for Cupid’s Undie Run, or starting your very own DIY event, you can party on knowing that you are making a difference and are part of finding a cure to #EndNF.

There are many other NF organizations out there, but we are the only one that specifically and whole-heartedly focuses on funding research. And it’s working. We work in alliance with our partner, the Children’s Tumor Foundation, a 4-star rated charity, and the world’s leader in NF research. Since our beginning, we’ve seen an increase in clinical trials, and those who participate in the trials are seeing real results. In eleven years, over 108,600 undie runners have joined our ranks, fundraising $21,700,000 to support our cause.
