WHY WE RUN IN OUR UNDIES
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.
