We run in our undies because those affected by NF can’t cover up their tumors. They can’t put on clothes to feel more comfortable, so why should we? Since 2010, we have brought together over 108,600 undie runners to build a community of supporters that just won’t quit. Our community has raised over $21,700,000 since the inception of Cupid’s Undie Run, with 100% of net proceeds funding NF research, through our partner the Children’s Tumor Foundation. And we are seeing real results, including a ground-breaking clinical trial where 70% of participants experienced 20-50% tumor reduction! But we aren’t even close to being done, and we won’t stop until we #EndNF.

Our Founding Story

In 2010, a group of do-gooders, led by co-founders Brendan Hanrahan, Chad Leathers and Bobby Gill, dropped their pants and ran through the D.C. cold to raise money for research to help end neurofibromatosis (NF), a rare genetic disorder that causes tumors to grow on nerves throughout the body. They ran in their undies because those affected with NF can’t cover up their tumors, so they decided to strip down in solidarity.

Since 2010, Cupid’s Charity was created and became a recognized 501(c)(3) non-profit with a mission to end NF by funding much needed research. We have raised over $21,700,000 to date, with 100% of net proceeds funding research through our partner the Children’s Tumor Foundation, the world’s leader in NF research.

Our mission is to accelerate the discovery of a cure for NF by inspiring our loyal community of supporters to do good year-round through boundary-pushing experiences. Everything we do is guided by our three core values:

1. Lead with Love

2. Innovate and Co-Create

3. Attitude is Everything
